Merging a few OJS 2 installations into a single OJS 3?

Hi,

I recommend the following:

  1. Upgrade all OJS2 installations to latest version of OJS2
  2. Merge the installations into one OJS2 installation with this excellent plugin: GitHub - lepidus/fullJournalTransfer: OJS plugin for importing/exporting a journal with all its private information (e.g. submitted articles, reviews, editorial decisions, etc.)
  3. Upgrade the merger installation to OJS3

And before every step take database and file back-ups of everything
