Additional SysAdmin Verifications

If a UMP 365 server is hardened through stricter Security policies and services are required to be white-listed, add the following services ( created when upgrading to version 8.0.450) to the white-list:
SysAdmin.QuickReplicationCycleWorker
SysAdmin.UMP.Watchdog
SysAdmin.SyncAcquiredNumber

See Managing the Replication Cycle for details on the above services.

Microsoft Graph PowerShell module is installed by the installation script (the AzureAD PowerShell module is approaching end-of-service). Consequently, ensure that any 3rd party Anti-virus software does not restrict the installation of the Microsoft Graph module.
Ensure that the SQL Server Management Studio’s server collation is correctly set to SQL_Latin1_General_CP1_CI_AS. If not, then a re installation of the SQL server is required to change the Server Collation.

Make sure all databases are backed up before removing the SQL server, so that they can be correctly restored (see Backing up UMP-365 – Disk Snapshot).
