Exchange 2007 SP2 to SP3

masdf123 used Ask the Experts™
Hi guys,

Currently running Exchange 2007 sp2 on Server 2003 r2.

Is it really needed/recommended to upgrade to sp3.

Will it be done by just running the sp3 setup on sp2?

I would probably recommend waiting to jump to 2010 as that will have all of the same features, but more. I personally have always had problems with service pack updates, but then again, if you're not planning on going to 2010, service pack 3 may be the better option.

As you can tell from here: http://technet.microsoft.com/en-us/library/aa996719.aspx under the Operating system requirement, Exchange 2010 doesn't run on any version of Windows 2003. so you'd have to upgrade to 2008 (which, to be honest, I highly recommend if it is possible for your budget).

That said, making sure that all of your operationally required software is fully updated is extremely important. Primarily for security, but also because of extra features, and the fact that SP3 is supposed to make Exchange 2007 not suck as much. And with *that* said, you should also approach it cautiously, making sure you have enough backup data and contingency plans in place should something go wrong.
