This is very weird. I can perfectly understand that you do a major upgrade you tested, and before launching openly, but by testing it on production environment, you see that the upgraded system has problems you didn't see in testing environment. But what do you do in such a case ?
Revert to backup of course ! You don't continue to twiddle on your production environment while you keep customers out. You only realized that your testing environment failed to be a good test bed, so you put back the old system, and you try to improve your test environment so that you can faithfully reproduce the problems you inadvertently saw during upgrade ! If you saw stuff in the production environment that you didn't see in the test environment, then you can't trust the upgrade, and you have to go back to the previous, working environment. You don't do testing on your production environment for days.
