Question : procedure for installing Exchange 2007 SP3 on CCR

Is there a specific procedure document for installing SP3 on an existing Exchange 2007 SP1 CCR?

I've got 2 nodes running the CCR, and one node running HUB and CAS.  This is the best document I've found for installing Exchange 2007 SP2:

Is the procedure the same for installing SP3?
Can I upgrade directly to SP3 from SP1, or does SP2 have to be installed first?
Thanks.
