We upgraded from 5.6 to 5.7.2 and struck most of the issues that had been thankfully posted by others and with the fixes. So a half hour of reading the forum when the issues were struck, saved us lost down time.

1) We only moved over the files that are listed as changed as the site is heavily customized. Had debug errors. Fix: Copy over all the bin/*.dlls
2) The cart and other pages failed. Fix: Renamed the bvkeys.config to bvkeys.old.config .

Question: I am pretty sure I copied over the files Configuration\PaymentWizard.aspx and Configuration\PaymentWizard.aspx but they were gone later. So I copied them back typed in the path to them as there appears to be no menu that gets to them. Are they only used on a new install when first configuring the site as the wizard they are called and are then deleted for security or other reasons??
