We just performed a migration from Server to Cloud.
Everything was imported correctly, except that some user cannot see all the contents of confluence.
In the user administration in Jira cloud, 6 Users appear in the confluence groups, the free plan is up to 10.
However, in another view, in the confluence group, it appears that we have 13 users ... could this be limiting access to viewing the workspaces?
several users are "migration" etc, how do we remove them to verify that it works correctly afterwards?
How to erase "migrate and chat " users? for example.

Thank you
