PolicyPkg.kmm provides a method to export and import the user prefs created by Policies Manager. This is an experimental release because I have only used the first version of Policies Manager. I do not know if later versions create more or different prefs. At this time the import function is a replace only. There is a backup option provided.
Because this is an experimental release, I highly recommend that you back up your prefs.js file before using this tool. The menu item for Policy packager is found under TOOLS.
tested without any problems on different profiles and different installations.. no bugs whatsoever. extremely useful extension, thanks james. policy packager has been added right under policies manager
