How to import reviews in OJS 3.1

At the moment we are migrating our journals from individual OJS platforms to a single multi-journal platform. Both individual platform and multi-journal platform are using OJS

We have exported all articles + users and imported them to the new platform. So far, so good. However, I’ve noticed, that all articles which are in the stage “externalReview” are not visible for the journal manager or journal editor in the new platform. I can see that there are 20 submissions “Unassigned”, but only 4 are shown (see screenshot). That’s because reviews and assigned reviewers were not imported. Is there any chance to import the reviews / the assigned reviewers? We can’t just copy the database from the old platform, because on the new multi-journal platform there are already journals online.


I’m having the same problem.
