I am trying to migrate an entire journal from an OJS 18.104.22.168 installation to another new OJS 3.1 installation.
The journal is in a database along with other journals, but I need to export it and import it to the new OJS 3.1 installation.
I have been reading for a while and I found this plugin GitHub - lepidus/fullJournalTransfer: OJS plugin for importing/exporting a journal with all its private information (e.g. submitted articles, reviews, editorial decisions, etc.).
Unfortunately, it seems not working with 3.x versions.
Which would be the best way to create an OJS installation from scratch with the data of the journal?
