We are running Exchange 2007 SP1 with Forefront for Exchange SP1. I need to install Forefront for Exchange SP2 on the Hub Transport and Mailbox servers. The mailbox servers are A/A/P using SCC. All servers are Windows 2008 SP2.
I guess to install Forefront SP2 on the Hubs it is a case of just running the setup.exe file, but how about the SCC nodes? Should I install on the passive nodes? Or does it need to be installed on the active nodes? I can't find anything on the internet about this.
Also, would people recommend installing on the Hubs first, seeing how this goes for a few days, then the mailbox servers, or should SP's be installed on all server roles at the same time?
Any help appreciated!
