We are upgrading from 7.5 to 8.0 and are receiving an error that appears to be a result of our custom scoring criteria. I've seen similar posts out there and sounds like there is a work a round for this. If anyone has a work around please share.
I had some problems during the upgrade: the upgrade failed when it reached the custom domains for portfolio scoring criteria. By investigating, I found out that the default domains (Risk and Value) are hardcoded in the upgrade scripts. Therefore, I deleted the domains from the 7.5 instance, performed the upgrade and recreated the domains in the 8.0 instance.
