What’s the final desired outcome here? Do you want to end up with a single OJS installation with everything in one place? Or do you just want to run a second OJS installation completely separate from the other one?
The latter is relatively easy to do. The former is not really possible if you want to preserve the workflow of submissions that are not yet published. OJS has plugins for exporting published content in XML format but there is no way to “merge” two OJS installations together.
Okay, so that’s not really possible with OJS, easily. The best you can manage here is to first upgrade your 126.96.36.199 site to 188.8.131.52 (to make the same as the live site), export your published content, and then import it into the other site. You’d lose any articles still in the workflow, and you’d also not be able to migrate any reviews or work done on the published articles during this process. Further your links may change since the newly imported articles will have new submission ids and the submission id is part of the URL when viewing an article in most cases.
Further, users would of course be another matter. Those usually get migrated separately but obviously you can’t import a user if that user’s username or email address already exists in the new installation.
