Problem:

How do I update the Cluster Witness and UPD location for an RDS farm?

Solution:

Changing the UPD file location

Open Server Manager> Remote Desktop Services> Collections> Click the drop down where it says Tasks and click edit.

Here you can change the UPD location under User Profile Disks. Ensure users are logged out before changing.
