I made the script change for the upgrade I'm running now and that one went fine through that step with no error.
On the previous upgrade, I did look at the changelog first. What I'm trying to figure out is if proceeding even though it gave me an error left a problem in my database. I.e. it's now 7.7.3 having encountered an error during install.
Is there anything I need to do by hand with MySQL to account for that SQL error in the install? Or is the system fine, and that error didn't matter?
