It looks very simple but what happens, if I accidently change into a GUID of another user. Or if the system generates another GUID later which conflicts with my arbitrarily chosen GUID.

I'm wondering if this method is also working with old versions of PI e. g. 1.2.21.

Has anyone experiences in changing IDs and playing older versions?
