Guys,
i have recently upgrade MDS from 2008R2 to 2017.
1. we made a backup of 2008R2 database and restored in in SQL 2017 and then do an upgrade.
when i try to add new users or update permissions on existing users that were restored from 2008 R2 MDS i get this error "The model permission cannot be saved. The object GUID is not valid. Correlatio"
also when i try to access Function mode it says access denied. i been doing research for ages and there is no solution on the internet. can someone please assist
