Hi,
I think the answer to my question is a yes, but I just wanted to confirm with your experience:
We are running Exchange 2010 Sp2 roll up3 and would like to install roll up 4. My plan is to install Roll Up 4 first on my 2 CAS servers one at a time on the same night then next day or in two days if all goes well, install Roll up 4 on my Hub Transport then Mailbox servers eventually.
Is this plan OK?
