要約

While trying to take a Jira Cloud backup for server, a warning appears about the presence of team-managed projects.

Team-managed projects are not supported when a backup is created for server, so they must be deleted. 

When "delete all team-managed projects" is clicked, a 500 internal server error appears.

Check if the team-managed projects were archived

If you see this error and are also unable to search for the team-managed projects listed manually, the projects are likely archived. 

1. Navigate to Settings > Projects > Archive
2. Restore each project individually
3. Move each restored project to the Trash
4. Visit Trash folder in Settings > Projects to delete them permanently
