ShareGate added me everywhere as Site Collection Administrator - how to undo?
Or, if you want to do it manually for each group, you can go to https://<tenant>.sharepoint.com/sites/<group>/_layouts/15/mngsiteadmin.aspx
Adding Benjamin Niaulin from Sharegate to see if he can help with this.
I've already received information from ShareGate Support on how to undo this.
Looks like you could undo this with ShareGate, but only if another account (possibly service account) has the permission to change the affected site collections.
I already undid my few group site permissions manually, since I didn't want any other account to have access, except the "Company Administrator" group.
Did they send it to you directly, or did they send you a link to a KB? If so could you post, I want to head the same problem off at the pass.
directly:
All you need to do is to go to the Reporting tool (wrong, it's the Explorer Section), select your environment that you wish to remove the permissions and click on the right-handside of the screen feature ''Remove Permissions''
In the next window, pick your user and select ''Remove Explicit Permissions'' and finally select ''Site Collection Administrator''. Once applied, you have just removed those access to your user account accross your environment.
Keep in mind that you won't have sufficient access rights to run reports in Sharegate anymore nor structural migration as expected.
