Can i upgrade from exchange 2010 SP1 directly to exchange 2010 SP3 rollup 14? Or do I need to upgrade to SP3 first and then install rollup 14?<br />
<br />
I have just installed this new exchange 2010 server and am working on getting it to coexist with my current exchange 2007 so I could migrate all other roles to it and retire exchange 2007. So I would like to know if it is all right to upgrade from SP1 directly to SP3 in this situation? <br />
<br />
I have no other email related servers and only one exchange 2007 that handles:<br />
<br />
Client Access server<br />
Hub Transport server<br />
Mailbox server
