Migrating Ansible content to a different collection
When you move content from one collection to another, for example to extract a set of related modules out of
community.general to create a more focused collection, you must make sure the transition is easy for users to follow.
Before you start migrating content from one collection to another, look at Ansible Collection Requirements.
To migrate content from one collection to another, if the collections are parts of Ansible distribution:
Copy content from the source (old) collection to the target (new) collection.
Deprecate the module/plugin with
removal_versionscheduled for the next major version in
meta/runtime.ymlof the old collection. The deprecation must be released after the copied content has been included in a release of the new collection.
When the next major release of the old collection is prepared:
remove the module/plugin from the old collection
remove the symlink stored in
plugin/modulesdirectory if appropriate (mainly when removing from
remove related unit and integration tests
remove specific module utils
remove specific documentation fragments if there are any in the old collection
add a changelog fragment containing entries for
breaking_changes; you can see an example of a changelog fragment in this pull request
meta/runtime.ymlin the old collection:
redirectto the corresponding module/plugin’s entry
in particular, add
redirectfor the removed module utils and documentation fragments if applicable
remove related entries from
tests/sanity/ignore.txtfiles if exist
remove changelog fragments for removed content that are not yet part of the changelog (in other words, do not modify changelogs/changelog.yaml and do not delete files mentioned in it)
remove requirements that are no longer required in
To implement these changes, you need to create at least three PRs:
Create a PR against the new collection to copy the content.
Deprecate the module/plugin in the old collection.
Later create a PR against the old collection to remove the content according to the schedule.
Create a PR in the new collection to:
Copy ALL the related files from the old collection.
If it is an action plugin, include the corresponding module with documentation.
If it is a module, check if it has a corresponding action plugin that should move with it.
meta/for relevant updates to
runtime.ymlif it exists.
Carefully check the moved
tests/unitsand update for FQCN.
tests/sanity/ignore-*.txtentries in the old collection.
meta/runtime.ymlin the old collection.
Create a PR against the source collection repository to remove the modules, module_utils, plugins, and docs_fragments related to this migration:
If you are removing an action plugin, remove the corresponding module that contains the documentation.
If you are removing a module, remove any corresponding action plugin that should stay with it.
Remove any entries about removed plugins from
meta/runtime.yml. Ensure they are added into the new repo.
Remove sanity ignore lines from
Remove associated integration tests from
tests/integrations/targets/and unit tests from
if you are removing from content from
community.network, remove entries from
meta/runtime.ymlfor any entries you may need to remove or update, in particular deprecated entries.
meta/runtime.ymlto contain redirects for EVERY PLUGIN, pointing to the new collection name.
Maintainers for the old collection have to make sure that the PR is merged in a way that it does not break user experience and semantic versioning:
A new version containing the merged PR must not be released before the collection the content has been moved to has been released again, with that content contained in it. Otherwise the redirects cannot work and users relying on that content will experience breakage.
Once 1.0.0 of the collection from which the content has been removed has been released, such PRs can only be merged for a new major version (in other words, 2.0.0, 3.0.0, and so on).
BOTMETA.yml, for example in community.general collection repository, is the source of truth for:
If the old and/or new collection has
BOTMETA.yml must be updated correspondingly.
Ansibulbot will know how to redirect existing issues and PRs to the new repo. The build process for docs.ansible.com will know where to find the module docs.
