Hi, I’m planning to merge two OJS installations into a new single OJS. Is there a version that is considered the most stable for this merging process? Are there any steps I should take before starting the import/export process?
If both OJS versions are 3.3.x or lower, you can leave them at the latest 3.3.x and use this plugin for a more complete import: GitHub - lepidus/fullJournalTransfer: OJS plugin for importing/exporting a journal with all its private information (e.g. submitted articles, reviews, editorial decisions, etc.)
I suggest importing the OJS with less content into the one that contains more.
