Move File Share Witness to another server

DAG is configured in my client’s Exchange environment and the file share witness is configured as a hub transport server. Due to the O365 migrations, the management has decided to cut short the number of on-premise servers. Hence, the current FSW server which also happen to be a CAS/HUB server was planned for decommission. So we had to move the FSW role to a different CAS/HUB server.

To confirm, execute the command:

Get-DatabaseAvailabilityGroup -Identity “DAGName” | Select Wi*
