After bad experience upgrading from 1.6.2 to 1.7.2 I want to downgrade to be able to work.
I have backup of the state before I upgraded, but since I upgraded we already used FengOffice before we realized that there is problem. I cannot run from backup as I would loose data.
What I have to do to make 1.6.2 run on top of this?
Thanks for any suggestion.
