Have a functional Server 2016 RDS Deployment consisting of RD Web Access (not using), RD Gateway, RD Connection Broker, RD Session Host on TS-01, RD Licensing on DC-01, and a 2nd Session Host on TS-02. There is one existing Collection serving up one RemoteApp program to both Session Hosts.
The TS-01 server needs to be redeployed from scratch due to an OS issue so I need to move the RD Web, RD Gateway, RD CB roles to the DC-01 server first, leaving the Session Host role in place on TS-01 for now.
I've seen articles about migration which I don't think apply here. I do not want to enable HA on this since I know you can't go back to non-HA. Can each role be deployed on the other server and then removed from the TS-01 server? Or is this a deploy from scratch scenario?
