How to move existing RAS installation to new machine from an old one?
In order to migrate your existing Remote Application Server installation, do the following:
Deploy a backup agent to New Machine:
- In RAS Console go to Farm > Publishing Agents (Backup Servers in v14.1) > click on +
Change New Machine's priority to Master:
- On the new server open Console go to Farm > Backup Servers > right-click on new added server > Promote Backup to Master
Change Parallels clients to point to new server:
- File > Add new connection...
Remove Old machine's RAS agents (Gateway, Publishing, etc.) using RAS Console in New Machine.
- Remove RAS from the Old Machine using Windows Control Panel
NOTE: Should the old master server act also as a Terminal Server Agent within your farm, if the goal is to decomission the old server, it is important to install the software published on a new Terminal Server and update the publishing rules to reflect the new installation.
