Upgrading from Nautobot v1.X

Pre-migration validation

In Nautobot 1.x, starting with 1.5.22, there is a nautobot-server pre_migrate command that can be run to check your existing data for compatibility with the data model changes introduced in Nautobot 2.0. You are highly encouraged to run this command before beginning to migrate to Nautobot 2.x as it will catch and report certain data-sanitization issues that cannot be remediated automatically during the migration and will need to be manually corrected before you upgrade.

For example, if any of the pre-migration checks fail, you may see an error message like this:

$ nautobot-server pre_migrate
>>> Running check: check_configcontext_uniqueness...
>>> Running check: check_exporttemplate_uniqueness...
>>> Running check: check_virtualchassis_uniqueness...
CommandError: One or more pre-migration checks failed:
    You cannot migrate ConfigContext or ConfigContextSchema objects that have non-unique names:
    - ConfigContext: [{'name': 'cc1', 'count': 2}]
    - ConfigContextSchema: [{'name': 'ccs1', 'count': 2}]

    You cannot migrate VirtualChassis objects with non-unique names:
     - [{'name': 'vc1', 'count': 2}]

Otherwise, a clean exit displays "All pre-migration checks passed." indicating that your Nautobot instance is ready to be upgraded to Nautobot 2.0:

$ nautobot-server pre_migrate
>>> Running check: check_configcontext_uniqueness...
>>> Running check: check_exporttemplate_uniqueness...
>>> Running check: check_virtualchassis_uniqueness...
All pre-migration checks passed.

Permission Constraint Migration

Permission constraints that contain references to fields or models that were changed or removed in Nautobot 2.0 will have to be updated manually after the upgrade. For example, any permission constraints that reference a Site will need to be updated to reference the Location model instead. The nautobot-server pre_migrate command will output a list of all permission constraints that need to be updated after the upgrade.

>>> Running permission constraint checks...

One or more permission constraints may be affected by the Nautobot 2.0 migration.
These permission constraints will have to be updated manually after upgrading to
Nautobot 2.0 to reference new models and/or values. Please review the following
warnings and make sure to document the objects referenced by these constraints
before upgrading:

ObjectPermission 'backbone devices' (id: ced686c3-2b34-4612-974a-bad766512661) has a constraint that references a model (nautobot.dcim.models.devices.DeviceRole) that will be migrated to a new model by the Nautobot 2.0 migration.
{
    "device_role": "e99adc77-40ef-4a0f-b2c1-26dbf6648ef1"
}

ObjectPermission 'example job run' (id: 41c6d03e-6388-47eb-b575-1c7a21725bc3) has a constraint that references a model field (nautobot.extras.models.jobs.Job.name) that may be changed by the Nautobot 2.0 migration.
{
    "name": "Example job, does nothing"
}

ObjectPermission 'emea' (id: 2d3b7aae-98ab-44ec-af89-43d3002a1b7d) has a constraint that references a model (nautobot.dcim.models.sites.Region) that will be migrated to a new model by the Nautobot 2.0 migration.
[
    {
        "site__region__slug": "emea"
    },
    {
        "id": "4c9f3e5c-2dc6-46f6-95ac-ac778369edfc"
    }
]

We recommend taking inventory of any objects referenced by primary key in permission constraints for the following models:

• dcim.DeviceRole
• dcim.RackRole
• extras.TaggedItem
• ipam.Aggregate
• ipam.IPAddress
• ipam.Prefix
• ipam.Role

This is because the primary key for these objects may be changed during the migration. You will not be able to use the primary key value from the old object in the constraint to find the new object.

Note

This pre-migration check only checks the last model referenced in a constraint filter. If you have nested filters (device_role__devices) they may not be reported by this check. You should review all of your permission constraints after the upgrade to ensure that they are still valid.

Examples

Primary keys for the migrated Site and Region objects were retained in the Location model, so you do not need to update the primary key value in any Site or Region constraints:

Old Constraint

{
    "site": "4c9f3e5c-2dc6-46f6-95ac-ac778369edfc"
}

New Constraint

{
    "location": "4c9f3e5c-2dc6-46f6-95ac-ac778369edfc"
}

Other models such as the DeviceRole that was migrated to Role did not retain the original primary key. In this case you will need to find the new object's primary key and update the constraint to reference the new model and new primary key value:

Old Constraint

{
    "device_role": "00000000-0000-0000-0000-000000000000"
}

New Constraint

{
    "role": "11111111-1111-1111-1111-111111111111"
}

You may also need to update field names in your permission constraints. For example, if you have a permission constraint that references the slug field on a model that was removed in Nautobot 2.0, you will need to update the constraint to reference a different field instead:

Old Constraint

{
    "slug": "router-01"
}

New Constraint

{
    "id": "5f96ac85-32d4-435d-84e4-66e631ae133f"
}

Some fields were only renamed without making any changes to the data so the constraint update will be a simple matter of updating the field name:

Old Constraint

{
    "circuit__type__name": "metro-ethernet-1000mb"
}

New Constraint

{
    "circuit__circuit_type__name": "metro-ethernet-1000mb"
}

Dependency Changes

• Nautobot no longer uses or supports the use of django-cryptography.
• Nautobot no longer uses or supports the use of django-mptt.
• Nautobot no longer uses or supports the use of django-rq.

App Developer Interface

All imports for app developers should now be sourced from nautobot.apps.* or provided models, as this is the supported public interface. This will help ensure proper SemVer is kept intact and provide a place to add new features without breaking existing integrations.

Database (ORM) Changes

Warning

Changes were made to model and related model fields. In some cases this may invalidate or make subtle changes to existing Permission Constraint filter data. Please review the Permission Constraint Migration section above for more information. These changes might also affect Filter Extensions you have written in your apps.

Database Field Behavior Changes

Most of the database field behavior changes in Nautobot 2.0 fall into the following general categories:

1. The created field on models has changed from a date only ("2023-04-06") to being a date/time ("2023-04-06T19:57:45.320232Z")
2. Various models that had a required site field and an optional location field now have a required location field.

Renamed Database Fields

Most renamed database fields in Nautobot 2.0 fall into the following general categories:

1. Renaming of foreign keys and reverse relations to more consistently and specifically match the related model name or plural name (for example, Circuit.terminations to Circuit.circuit_terminations, Rack.group to Rack.rack_group)
2. Renaming of tree model fields for consistency and due to the change from django-mptt to django-tree-queries (for example, InventoryItem.child_items to InventoryItem.children and InventoryItem.level to InventoryItem.tree_depth)

1. Removal of references to removed models such as Site and Region
2. Removal of slug fields in preference to the use of natural keys.
3. Removal of django-mptt internal fields (lft, rght, tree_id)

Info

For more information on how to update your integrations after the removal of slug fields, see Uniquely Identifying a Nautobot Object.

Replaced Models

Generic Role Model

The ipam.Role, dcim.RackRole, and dcim.DeviceRole models have been removed and replaced by a single extras.Role model. This means that any references to the removed models in the code now use the extras.Role model instead.

Removed Model	Replaced With
dcim.DeviceRole	extras.Role
dcim.RackRole	extras.Role
ipam.Role	extras.Role

Site and Region Models

The dcim.Region and dcim.Site models have been removed and replaced by dcim.Location model. This means that any references to the removed models in the code now use the dcim.Location model instead with LocationType "Site" and "Region".

Important

If you are a Nautobot App developer, or have any Apps installed that include data models that reference Site or Region, please review the Region and Site Related Data Model Migration Guide to learn how to migrate your apps and models from Site and Region to Location.

Removed Model	Replaced With
dcim.Region	dcim.Location
dcim.Site	dcim.Location

Aggregate Migrated to Prefix

The ipam.Aggregate model has been removed and all existing Aggregates will be migrated to ipam.Prefix records with their type set to "Container". The Aggregate.date_added field will be migrated to Prefix.date_allocated and changed from a Date field to a DateTime field with the time set to 00:00 UTC. Aggregate.tenant, Aggregate.rir and Aggregate.description will be migrated over to the equivalent fields on the new Prefix. ObjectChanges, Tags, Notes, Permissions, Custom Fields, Custom Links, Computed Fields and Relationships will be migrated to relate to the new Prefix as well.

If a Prefix already exists with the same network and prefix length as a previous Aggregate, the rir and date_added fields will be copied to the rir and date_allocated fields on the existing Prefix object. Messages will be output during migration (nautobot-server migrate or nautobot-server post_upgrade) if the tenant, description or type fields need to be manually migrated.

Aggregate	Prefix
broadcast	broadcast
date_added	date_allocated
description	description
network	network
prefix_length	prefix_length
rir	rir
tenant	tenant

Prefix Parenting Concrete Relationship

The ipam.Prefix model has been modified to have a self-referencing foreign key as the parent field. Parenting of prefixes is now automatically managed at the database level to greatly improve performance especially when calculating tree hierarchy and utilization.

As a result of this change, it is no longer necessary nor possible to disable tree hierarchy using settings.DISABLE_PREFIX_LIST_HIERARCHY as this setting has been removed. Additionally it is no longer possible to disable global uniqueness using settings.ENFORCE_GLOBAL_UNIQUE as this setting has been removed.

The following changes have been made to the Prefix model.

Removed	Replaced With
get_child_prefixes()	descendants()

Prefix Parenting Guidance

The following guidance has been added for the Prefix model in order to ensure more accurate network modeling:

• A Prefix of type Container should only have a parent (if any) of type Container
• A Prefix of type Network should only have a parent (if any) of type Container
• A Prefix of type Pool should only have a parent (if any) of type Network
• Any Prefix can be a root prefix (i.e. have no parent)

In Nautobot 2.0, creating or updating prefixes that violate this guidance will result in a warning; in a future Nautobot release this will be changed to an enforced data constraint.

IPAddress Parenting Concrete Relationship

The ipam.IPAddress model has been modified to have a foreign key to ipam.Prefix as the parent field. Parenting of IP addresses is now automatically managed at the database level to greatly improve performance especially when calculating tree hierarchy and utilization.

IPAddress Parenting Guidance

The following guidance has been added to the IPAddress model:

• An IPAddress should have a parent Prefix of type Network
• An IPAddress should not be created if a suitable parent Prefix of type Network does not exist
• An IPAddress can be a member of a Pool but only if the Pool is a child of a Network

As with the Prefix parenting guidance above, violating this guidance in Nautobot 2.0 will result in a warning; in a future Nautobot release this will be changed to an enforced data constraint.

Prefix get_utilization Method

The get_utilization method on the ipam.Prefix model has been updated in 2.0 to account for the Prefix.type field. The behavior is now as follows:

• If the Prefix.type is Container, the utilization is calculated as the sum of the total address space of all child prefixes.
• If the Prefix.type is Pool, the utilization is calculated as the sum of the total number of IP addresses within the pool's range.
• If the Prefix.type is Network:
  • The utilization is calculated as the sum of the total address space of all child Pool prefixes plus the total number of child IP addresses.
  • For IPv4 networks larger than /31, if neither the first or last address is occupied by either a pool or an IP address, they are subtracted from the total size of the prefix.

Example

• 192.168.0.0/16 Container - 1024/65536 utilization
  • 192.168.1.0/24 Network - 1/254 utilization
    • 192.168.1.1 IP Address
  • 192.168.2.0/24 Network - 4/256 utilization
    • 192.168.2.0/30 Pool - 1/4 utilization
      • 192.168.2.1 IP Address
  • 192.168.3.0/24 Network - 5/254 utilization
    • 192.168.3.1 IP Address
    • 192.168.3.64/30 Pool - 0/4 utilization
  • 192.168.4.0/24 Network - 1/256 utilization
    • 192.168.4.255 IP Address

GraphQL and REST API Changes

API Behavior Changes

Most of the API behavior changes in Nautobot 2.0 fall into the following general categories:

1. The created field on most models has changed from a date only ("2023-04-06") to being a date/time ("2023-04-06T19:57:45.320232Z")
2. The status fields on various models has changed from a pseudo-enum value (containing a "value" and a "label") to referencing the related Status object in full, similar to other foreign-key fields.
3. Various models that had a required site field and an optional location field now have a required location field.

Removed 1.X Version Endpoints and Serializer Representations

Nautobot 2.0 removes support for 1.X versioned REST APIs and their Serializers. Requesting older API versions will result in a 400 Bad Request error.

Please ensure you are using the latest representations of request/response representations as seen in the API docs or Swagger.

Replaced Endpoints

These endpoints /ipam/roles/, /dcim/rack-roles/ and /dcim/device-roles/ are no longer available. Instead, use the /extras/roles/ endpoint to retrieve and manipulate role data.

Removed Endpoints	Replaced With
/dcim/device-roles/	/extras/roles/
/dcim/rack-roles/	/extras/roles/
/ipam/roles/	/extras/roles/

New Interface to IP Address Relationship Endpoint

The through table (ipam.IPAddressToInterface) for the IPAddress to Interface/VMInterface many-to-many relationship has been exposed through the REST API at /api/ipam/ip-address-to-interface/. This endpoint must be used to create, retrieve, update, and delete relationships between IP addresses and interfaces through the REST API. Each ipam.IPAddressToInterface object maps a single ipam.IPAddress object to a single dcim.Interface or virtualization.VMInterface object. When creating relationships through this endpoint, the ip_address field is required and one of interface or vm_interface is required. There are additional boolean fields (is_primary, is_default, etc.) exposed through the REST API that may be used if desired but are not currently implemented in the Nautobot UI.

API Query Parameters Changes

Nautobot 2.0 removes the ?brief query parameter and adds support for the ?depth query parameter. As a result, the ability to specify brief_mode in DynamicModelChoiceField, DynamicModelMultipleChoiceField, and MultiMatchModelMultipleChoiceField has also been removed. For every occurrence of the aforementioned fields where you have brief_mode set to True/False (e.g. brief_mode=True), please remove the statement, leaving other occurrences of the fields where you do not have brief_mode specified as they are. Please see the documentation on the ?depth query parameter for more information.

UI, GraphQL, and REST API Filter Changes

Warning

Sweeping changes were made to model filter fields. In some cases this may invalidate or make subtle changes to existing DynamicGroup, GraphQLQuery or Relationship instances' filter data. Please utilize the nautobot-server audit_dynamic_groups and nautobot-server audit_graphql_queries helper commands when you are cleaning up DynamicGroup and GraphQLQuery filter data. You should run this command after your Nautobot instance is upgraded to v2.x successfully. The helper commands will not catch all possible issues, but they will catch some common ones. You should review all of your DynamicGroup filter data and GraphQLQuery query data after the upgrade to ensure that they are still valid. At the time of this writing, an audit helper command for Relationship filter data is not yet available.

Removed Changelog URL from View Context

changelog_url is no longer provided in the ObjectView context. To get a model instance's changelog URL, you can retrieve it from the instance itself if it supports it: model_instance.get_changelog_url().

Renamed Filter Fields

Most renamed filter fields in Nautobot 2.0 fall into the following general categories:

1. The tag filter is renamed to tags on all models supporting Tags.
2. Renames to match renamed model/serializer fields as described earlier in this document.
3. Related membership filters are renamed to has_<related> throughout, for example ConsolePort.cabled is renamed to ConsolePort.has_cable.
4. Most <related>_id filters have been merged into the corresponding <related> filter (see "Enhanced Filter Fields" below).

Enhanced Filter Fields

Below is a table documenting enhanced filter field changes in Nautobot 2.0. These enhancements mostly fall into the following general categories:

1. Many filters are enhanced to permit filtering by UUID or by name.
2. Filters that previously only supported a single filter value can now filter on multiple values.

Corrected Filter Fields

Below is a table documenting corrected filter field changes in Nautobot 2.0. These corrections mostly involve filters that previously permitted filtering on related membership only (/api/dcim/devices/?console_ports=True) and have now been corrected into filters for related membership (/api/dcim/devices/?has_console_ports=True) as well as by actual related objects (/api/dcim/devices/?console_ports=<UUID>).

Full table of corrected filter fields

Model	Filter	Correction
CustomFieldChoice	custom_field	Filter by UUID or key
Device	console_ports	Split into has_console_ports and console_ports filters
Device	console_server_ports	Split into has_console_server_ports and console_server_ports filters

Device	rear_ports	Split into has_rear_ports and rear_ports filters
IPAddress	parent	The parent filter now checks for an exact match of the parent Prefix; for legacy net_host_contained behavior now use the new prefix filter instead

Removed Filter Fields

Below is a table documenting removed filter field changes in v2.x. Most removed database fields in Nautobot 2.0 fall into the following general categories:

1. Removal of *_id=<uuid> filters as they have have been merged into filters that support both uuid and name/slug (for example, instead of /api/circuits/circuits/?provider_id=<UUID>, use /api/circuits/circuits/?provider=<uuid>).
2. Removal of filtering on removed models such as Region and Site. (Use location filters instead.)
3. Removal of slug filters from models that no longer have a slug field.

Removed Python Code

• Because of the replacement of the ?brief REST API query parameter with ?depth and the removal of all Nested*Serializers, some of the classes and mixins are removed because they are no longer needed.
• With the reimplementation of CSV import and export, CSVForm classes are generally no longer needed, and so a number of related mixin classes have been removed.

Git Data Source Changes

The Configuration Contexts Metadata key schema has been replaced with config_context_schema. This means that any schema references in your git repository's data must be updated to reflect this change.

GitRepository sync operations are now Jobs. As a result, when creating a new GitRepository it is not automatically synchronized. A GitRepository.sync() method has been implemented that will execute the sync job on a worker and return the JobResult for the operation. This method takes dry_run and user arguments. The dry_run argument defaults to False; if set to True will cause the sync to dry-run. The user argument is required if a sync is performed.

Additionally, the GitRepository.save() method no longer takes a trigger_resync=<True|False> argument as it is no longer required. The act of creating a new GitRepository no longer has side effects.

Below is a table documenting changes in names for Git-related Jobs. There should NOT be a need to ever manually execute the jobs due to the addition of GitRepository.sync(), but this is being provided for clarity.

nautobot.extras.datasources.git.pull_git_repository_and_refresh_data	nautobot.core.jobs.GitRepositorySync
nautobot.extras.datasources.git.git_repository_diff_origin_and_local	nautobot.core.jobs.GitRepositoryDryRun

Logging Changes

Where applicable, logging.getLogger("some_arbitrary_name") is replaced with logging.getLogger(__name__) or logging.getLogger(__name__ + ".SpecificFeature").

Below is a table documenting changes in logger names that could potentially affect existing deployments with expectations around specific logger names used for specific purposes.

Job Database Model Changes

The Job name field has been changed to a unique field and the name + grouping uniqueness constraint has been removed. The processes that refresh jobs (nautobot-server post_upgrade and nautobot-server migrate) have been updated to gracefully handle duplicate job names.

Example

class NautobotJob1(Job):
    class Meta:
        name = "Sample job"

class NautobotJob2(Job):
    class Meta:
        name = "Sample job"

These jobs would be named Sample job and Sample job (2)

The Job slug, source and git_repository fields have been removed. The Job module_name field will automatically be updated, for Jobs derived from a Git repository, from <submodule_name> to <git_repository_slug>.jobs.<submodule_name>. This also changes the secondary uniqueness constraint for Jobs to simply [module_name, job_class_name].

The Job class_path attribute has been simplified correspondingly, to simply <module>.<ClassName> instead of the former <source>/<module>/<ClassName>. For example, the Nautobot Golden Config backup job's class_path will change from plugins/nautobot_golden_config.jobs/BackupJob to nautobot_golden_config.jobs.BackupJob.

The Job commit_default field has been renamed to dryrun_default and the default value has been changed from True to False. This change is a result of the fundamental job changes mentioned in the Job Changes section below.

JobResult Database Model Changes

The JobResult objects for which results from Job executions are stored are now automatically managed. Therefore job authors must never manipulate or save() these objects as they are now used internally for all state transitions and saving the objects yourself could interfere with and cause Job execution to fail or cause data loss.

Therefore all code that is calling JobResult.set_status() (which has been removed) or JobResult.save() must be removed.

Job Changes

Migrating Jobs From v1 to v2

Changed in version 2.0.0

See Migrating Jobs From Nautobot v1 for more information on how to migrate your existing jobs to Nautobot v2.

Fundamental Changes

The BaseJob class is now a subclass of Celery's Task class. Some fundamental changes to the job's methods and signatures were required to support this change:

• The test_* and post_run methods for backwards compatibility to NetBox scripts and reports were removed. Celery implements before_start, on_success, on_retry, on_failure, and after_return methods that can be used by job authors to perform similar functions.

Important

Be sure to call the super() method when overloading any of the job's before_start, on_success, on_retry, on_failure, or after_return methods

• The run method signature is now customizable by the job author. This means that the data and commit arguments are no longer passed to the job by default and the job's run method signature should match the the job's input variables.

Example

class ExampleJob(Job):
    var1 = StringVar()
    var2 = IntegerVar(required=True)
    var3 = BooleanVar()
    var4 = ObjectVar(model=Role)

    def run(self, var1, var2, var3, var4):
        ...

Database Transactions

Nautobot no longer wraps the job run method in an atomic database transaction. As a result, jobs that need to roll back database changes will have to decorate the run method with @transaction.atomic or use the with transaction.atomic() context manager in the job code.

With the removal of the atomic transaction, the commit flag has been removed. The ability to bypass job approval on dryrun can be achieved by using an optional dryrun argument. Job authors who wish to allow users to bypass approval when the dryrun flag is set should set a dryrun attribute with a value of DryRunVar() on their job class. DryRunVar can be imported from nautobot.extras.jobs.

Example

from nautobot.extras.jobs import DryRunVar, Job

class ExampleJob(Job):
    dryrun = DryRunVar()

    def run(self, dryrun):
        ...

A new supports_dryrun field has been added to the Job model and Job class that returns true if the Job class implements the dryrun = DryRunVar() attribute. This is used to determine if jobs that require approval can be dry run without prior approval.

The commit_default job field has been renamed to dryrun_default and the default value has been changed from True to False.

Important

The read_only job field no longer changes the behavior of Nautobot core and is left to the job author to decide whether their job is read only.

Important

Nautobot no longer enforces any job behavior when dryrun is set. It is now the job author's responsibility to define and enforce the execution of a "dry run".

Request Property

The request property has been changed to a Celery request instead of a Django web request and no longer includes the information from the web request that initiated the Job. The user object is now available as self.user instead of self.request.user.

URL Changes

The Job URL path jobs/results/<uuid:pk>/ and URL pattern name job_jobresult are removed. Use URL path job-results/<uuid:pk>/ and URL pattern name jobresult instead. Any extras:job_jobresult references should be removed and be replaced by extras:jobresult.

The Job URL path /extras/jobs/<str:class_path>/ and associated URL pattern name extras:job are changed to URL path /extras/jobs/<str:class_path>/run/ and the URL pattern is renamed to extras:job_run_by_class_path. Conversely, the Job detail view URL pattern name extras:job_detail has been renamed to extras:job for consistency with other object detail view URL patterns.

Function Changes

Changed as_form_class, as_form and validate_data functions on BaseJob Model to classmethods so that they can be called directly from the class without needing to instantiate the Job in order to access them.

Function Renames

JobDetailView is renamed to JobView.

JobView is renamed to JobRunView.
