Database error on upgrade OJS 2.4.8.1 to OJS 3.0.2

Hi @Lazar_Stosic,

It looks like you’re moving ahead with an import/export approach based on this thread. But I’m wondering why you might be getting different errors when performing the upgrade – restoring from backup and performing the same steps twice should result in the same outcome. It’ll be a lot easier to debug if this is systematic.
