We are using the a few OJS 2 systems: one system for one magazin. We started in this way in the beginning to be possible to personalize the webpage and the rights journal by journal by modifying the editor’s and author’s templates and also the classes, etc. It was okay, but now we have more and more journals…
I found at PKP Frequently Asked Questions that it’s much easier to start with a single copy of OJS than to try to merge several OJS installations into one multiple page. However, what do you think, what are the possibilities for merging these multiple OJS 2 systems into a single OJS 3 installation?
