I just managed to get all the sign ups from version 2 of OJS to version 311.
Now, I am trying to automatically translate the XML of an edition that is exported from the version 2 of OJS to the version OJS311. The past edition can be found here (http://periodicos.unb.br/index.php/physicae) and the new edition can be found here (http://periodicos.unb.br/ojs311/index.php/physicae/). I managed to almost get the result, but I am still getting the following messages:
one for each one of the submission files (except the first!). Since the past version does not export ids (of any kind), I have just used the same id values in each xml block related to articles. Most probably this is the problem, but I have changed the ids ‘by hand’ to try to overcome this and I still kept receiving the same error message (an information: the edition was already remade by hand in the OJS311 site and it is already there, which issues the error * ##plugins.importexport.native.import.error.issueIdentificationDuplicate##, but, of course, I will exclude this handmade edition if I get this translation operational).
What should be the problem? (I can send both xml files - last version and its translation, but they are 4.2Mbytes long and maybe the issue is much easier to solve without looking at them.
Best regards, Olavo
