I was only indirectly involved but as I recall, it's pretty much that simple - one thing to look out for is which clients can talk to which server version - as I recall, we had to ensure that all the clients were upgraded before moving users. Also, check versions if you have Blackberry users connecting via Enterprise Messenger.

We need to move to Office Communication Server 2007. Currently I don't need more than a single server as the main use will remain just IM, but we will add other services soon. Has someone performed a simple upgrade like this? Is it just as simple as installing OCS 2007 and moving the users? Or do I need to do a more complicated install with multiple OCS 2007 servers with different roles? -- Bob Fronk b...@btrfronk.com
