I work in an organization that is running 3 or four different instances of Fusionpbx with different versions. I am currently looking to consolidate. The configuration is not too complicated but how would I go about importing historical voicemail from each instance onto a single instance. I was looking to rsync or copy the /var/lib/freeswitch/storage/voicemail/default directories over, but there is a reference to UUID. Is there a process for this?
