The script cannot execute these lines, and I have no idea why. Having a different database owner and object qualifier shouldn't break the upgrade.

The errors I'm getting are one page back, you can see them if you view the first page of this thread. Didn't want to paste them again. At the end of the stack trace, you will see an sql command. that command generates the commands I pasted the second time which gives those error messages on the first page (wow that was a weird sentence :) )
