migrating to new server - users and players disappear

I copied the /var/subsonic folder (ubuntu pc to debian pc) as described in another forum topic about migrating to a new server. Most of the settings (such as themes, display properties) moved over with no problems, but the users/passwords and players were not migrated.
Are there more folders that need to moved to the new server?
thanks,
Dan
