Upgrading from ConfigMgr 1702 to 1706 gives you “Microsoft SQL Server reported SQL message 2627, severity 14” in your status messages
If you upgraded your ConfigMgr 1702 or earlier environment to Configmgr 1706 and in the status messages after the upgrade you get :
Microsoft SQL Server reported SQL message 2627, severity 14: [Microsoft][SQL Server Native Client 11.0][SQL Server]Violation of PRIMARY KEY constraint ‘SUM_DriverUpdates_PK’. Cannot insert duplicate key in object ‘dbo.SUM_DriverUpdates’. The duplicate key value is (d8483f4f-0390-49db-b251-faf884dd8eaf
Be aware that the Product Group are aware of this issue and are on a working on a fix. The result of this problem is that admins cannot see new Surface driver updates.
Other than that, nothing else is impacted so it can be ignored.
Hope it helps ,
