Andy Grognan has written up an excellent guide on updating your Exchange 2007 CCR cluster to Service Pack 1. You can find his article at the following URL:

One of the things the TechNet doc does not state, is you have to make a registry modification to enable streaming backups which are now disabled by default in SP1. CCR uses the streaming backup functionality to do seeding. This is written in the release notes, but not on the TechNet guide for some odd reason.
