"Upgrading Exchange 2007 from Windows Server 2003 to Windows Server 2008

When upgrading standalone servers, it is not supported to upgrade your
operating system to Windows Server 2008 and then upgrade Exchange 2007 to
SP1. It is also not supported to upgrade Exchange 2007 to SP1 and then
upgrade your operating system to Windows Server 2008. To deploy Exchange
2007 SP1 on Windows Server 2008, you must install Windows Server 2008 on a
computer that does not have Exchange installed, and then install Exchange
2007 SP1.

For clustered mailbox servers, Exchange SP1 introduces support for
clustered mailbox servers running on Windows Server 2008. However, as a
result of the significant changes introduced in Windows Server 2008
failover clusters (called server clusters in previous versions of
Microsoft Windows), rolling upgrades of a failover cluster from Windows
Server 2003 to Windows Server 2008 are not possible. Therefore, to upgrade
a clustered mailbox server from Windows Server 2003 to Windows Server
2008, you must build a new failover cluster using Windows Server 2008 as
the operating system for all nodes, and then migrate the data from the old
cluster to the new cluster. You can use the Move Mailbox operation to move
mailboxes from the old cluster to the new cluster, and you can use public
folder replication to move any public folder data from the old cluster to
the new cluster."

I'll never understand how Exchange got so much market share...
