Moving a Site with UAM

We are experiencing problems when moving a WordPress installation from one URL to another. What happens is that the File Protection feature of UAM locks down all files for everyone, no matter the settings in the admin. The files are even locked away for the administrators logged into the admin.
We have tried moving the site by copying its files and database using a backup plugin called “Updraft”, and we have tried to simply change web server and DNS settings and thereby moving the site to a new URL without actually moving any files, and the result is the same in both cases.

Is there a recommended way to move a WordPress Site with UAM installed?
