Hi
I have stated upgrading form OJS 2.x to 3.x, and unfortunately it get failed. I did not take the backup of old database, my mistake.
At present my database is somewhere in the middle of upgrade. My OJS 2.x is working fine but I am unable to upgrade to OJS 3.x.
Can you help me in this regard, please?
Regards
Hi @asmecher,
This error appears when I upgraded ojs24 to ojs3.1.2, please help me.
Errors occurred during installation:
- A database error has occurred: Column âreview_round_idâ cannot be null
Hi @Duong_Duc_Hung,
There are several other threads in this forum about that same error message; Iâd suggest starting with the solutions recommended there, and if that doesnât work, post on a new topic describing what youâve tried and what the result was.

Hi @ThomasHarvey,
My apologies for the delay in responding. This is unfortunately a tough situation to fix â do you know where in the upgrade process the failure occurred? (Did you get an error message?)
