Our original server is an openSUSE 12.3 machine running Pydio 6.0.8 ZIP archive install with PHP5; the data directory is in another location out of the web path. I dumped the axjp database to a file, performed a Pydio 6.0.8 ZIP install on a new server running openSUSE Leap 15 (which only has PHP7 available), imported the database into it and was unable to get the site to work because mcrypt isn’t available in PHP7.
I then created an interim server running openSUSE Leap 42.3 with PHP5. I installed Pydio 6.0.8 on it, imported the database from the original server and successfully upgraded it to Pydio 8.2.1.
Now I’m stuck: the in-app upgrade to Pydio 8.2.2 fails on the interim 42.3/PHP5 server. If I dump the database and import it to the Leap 15/PHP7 server with a fresh install of Pydio 8.2.1, the users and workspaces look to be there, but all the shares appear to be gone.
