Automatic seat removal

GitLab Duo add-on seats are removed automatically to ensure only eligible users have access. This happens when there are:

  • Seat overages
  • Blocked, banned, and deactivated users

At subscription expiration

If your subscription containing the GitLab Duo add-on expires, seat assignments are retained for 28 days. If the subscription is renewed, or a new subscription containing GitLab Duo is purchased during this 28-day window, users will be automatically re-assigned.

At the end of the 28 day grace period, seat assignments are removed and users will need to be reassigned.

For seat overages

If your quantity of purchased GitLab Duo add-on seats is reduced, seat assignments are automatically removed to match the seat quantity available in the subscription.

For example:

  • You have a 50 seat GitLab Duo Pro subscription with all seats assigned.
  • You renew the subscription for 30 seats. The 20 users over subscription are automatically removed from GitLab Duo Pro seat assignment.
  • If only 20 users were assigned a GitLab Duo Pro seat before renewal, then no removal of seats would occur.

Seats are selected for removal based on the following criteria, in this order:

  1. Users who have not yet used Code Suggestions, ordered by most recently assigned.
  2. Users who have used Code Suggestions, ordered by least recent usage of Code Suggestions.

For blocked, banned and deactivated users

Once or twice each day, a CronJob reviews GitLab Duo seat assignments. If a user who is assigned a GitLab Duo seat becomes blocked, banned, or deactivated, their access to GitLab Duo features is automatically removed.

After the seat has been removed, it becomes available and can be re-assigned to a new user.
