Hey
We are facing same issue as mentioned above. But we are upgrading Sccm from 1610 to 1702. We have managed to upgrade primary site and one of our secondary site.
But while upgrading rest of the secondary sites we receive above mentioned errors.
Post which we verified above errors and we meet all criteria's. I mean we have the same collation at primary site and secondary site.
We have no permission issue, account has been given sysadmin rights. Still we get above errors.
So can you suggest us the solution for it.
