We have 5 servers, all win 2003 std (DC and File server, Exchange, Sql and Terminal Servers). I was planning to install Service Pack 2 on Exchange to get IMF V2.0. But apparently it turns out these servers are not running SP1 for win 2003 std. So I have to install SP1 on Win 2003 and then install SP2 on Exchange.
Now we don't have any comprehensive back up strategy (like Acronis or Norton) for backing up the servers and bringing it back in case of failed or botched SP install. How risky is it do it without backing it up or is there a way to back it up using win back up (I know we can do System State, ASR).
Also is it ok to just upgrade the server running Exchange to SP1 and then install SP2 and leave the rest of the servers as it is (without installing SP1)? or will there be conflicts if one is running SP1 and the others are not (especially DC will not be). And later do them after setting Acronis up.
I need SP2 for IMF v2.0 on exchange for custom filtering. SPAM has become very annoying. Any ideas/suggestion/solutions will be greatly appreciated. Thanks.
