I'm about to install a new server into our current tree.

We have 7 OES2 servers that will be upgraded to SP1 later this year.

Can i install OES2 SP1 on the new server without creating problems, or should i install OES2 without SP1 and upgrade later with the other servers?

Here in our HQ the server has replicas of all the other servers. Should this be upgraded first and then the other servers or is the order completely irrelevant?
