Dear Atlassian Users,
Please vote for these two feature requests that will make Atlassian Organizational Admin life a little easier.
The first one is to allow admins to migrate data from one to instance to another without Users or groups.
The second one is to allow admins to list out all "Managed" accounts from the "Users" panel, currently you have to download the CSV export from Active users and Managed accounts and compare them both manually to find out the "Active" users count vs "Managed" users count in your organization.
