For reasons (issues with the old HA version using BDR/syncthing - see separate thread) we were stuck on an ancient version of Fusion PBX (4.4 master) on Debian 9 with Freeswitch 1.10 and PHP 7.1.
Now we are wondering how best to get to a relatively current release.
First thought was to set up a current system from scratch and import the database, but it yields errors probably due to the missing schema updates in between and syntax differences between old and new PHP.
Otherwise we would try to update step by step, but we are missing a timeline, i.e. in between which Fusion versions we should do the Debian, Freeswitch and PHP updates.
