Code:
Upgrading from 3.1.3_GA_474 to 3.1.2_GA_445
From the log (I often don't read all the way), but it looks like the DB is 3.1.3.
It is STRONGLY not advised you downgrade. It's entirely possible you could break everything.
Rather than using the 3.1.2 package, just use the 3.1.3 or higher.
I would reccomend you upgrade your production server to 3.1.4. Here's a summary of the fix levels:
3.1.4 Major bugfixes 27-Jun-2006 23:55
3.1.3 Minor bugfixes 13-Jun-2006 13:43
3.1.2 Major bugfixes 31-May-2006 17:12
3.1.1 Major bugfixes 11-May-2006 21:36
