I've installed Microsoft's Web Farm Framework on a cluster of 4 web servers. I need to take the primary down to reinstall the OS and I want to change the primary server to one of the other servers. The WFF controller is installed on the primary.
I found it easy enough to designate one of the secondary servers as primary. In IIS Manager, under the correct server farm node, right-click on the server that I want to make primary and select "Designate as Primary Server".
The question is, how do I designate a new server as the controller? Can I move/copy the existing server farms? Or do I need to create new server farms and delete it from the old controller? Any other advice?
