I’m trying to export and import issues from one OJS instance to another.
The problem is that the exporter OJS is newer (3.3.0.6) and the import OJS is a bit older version (3.2.1.4). I get a lot of errors like this:
Element ‘{http://pkp.sfu.ca}submission_file’, attribute ‘created_at’: The attribute ‘created_at’ is not allowed.
or something like this
Element ‘{http://pkp.sfu.ca}name’: This element is not expected. Expected is ( {http://pkp.sfu.ca}revision ).
Is there anything I can do to migrate from first instance to another? I must point out, it is out of my options to install newer version of OJS on the import side, it is part of the bigger platform and I can not control that part.
thank you
