ocProducts cannot make any guarantees about the speed of which any new bugs might be patched, for this upgrade or any other upgrade. It is your own responsibility to make and test a full website backup (files and database) before you upgrade, for use in the unlikely event of you wanting to revert your upgrade. Some users may wish to test upgrades (and pre-fix any theme compatibility problems that could occur) on a staging site (a private mirror of their live site).
If you don't follow our advice by taking and testing a backup, and end up needing emergency repair help, ocProducts can help charged at our hourly rate.
