# What this PR does
This is a follow up to #2502 which started to remove logic to
"archiving" alert groups. This PR:
- removes all references to `AlertGroup.is_archived` and marks the
column as deprecated. We will remove it in the next release
- removes the `AlertGroup.unarchived_objects` `Manager`
- renames the `AlertGroup.all_objects` `Manager` to `AlertGroup.objects`
