Until now, we have used Jira Internal Directory for user management of all users.
I did now add a Microsoft Active Directory (Read Only, with Local Groups), and given that the highest priority.
This directory contain all company users. The usernames are the same as in the internal directory.
Now I want to remove all internal users that now have became shadow duplicates of those in the new Microsoft AD Directory.
However, I don't want to remove/disable the internal directory, because that contain all customer users, admin user, and some inbox accounts. Those shall remain internal.
I suppose I need to run a delete query on the db, and I need advise in order to do a safe removal.
