I have an existing wiki at version 1.23.2 which no longer runs as my ISP has moved on the minimum version of php supported to 7.x
I'm installing mediawiki 1.41.0 along-side this, but will need to migrate my old data. What's the easiest way to do this? I'm currently transferring all the new files over via FTP but not sure what the next step is to either just point the new wiki to the old database, or (if the databases are incompatible) how to migrate the data over to a new database of the required format.
Also what about images?
Any help appreciated.
