I did the same with only 2 issues (atleast issues for us

):
1. Errors get reported on duplicate Cust POs when entering an SO (we use STOCK as a Cust PO sometimes, and it will show each and every duplicate via an error screen...if you have 100 duplicate Cust POs for that customer, you will recieve 100 little error messages that you'll need to close)....I've posted an additional thread to try to fix this issue, only responses are to update to EVO.
2. UMs now show on packing lists, it was an issue for us, however through ModifyForms in DBA, you're able to remove it w/o issues.
These were the only 2 "issues" we've had when upgrading.
