We're currently on Exchange 2007 SP1, rollup 1. What would be the best update route. From SP1 to SP2, then SP3 or can we go from SP1 to SP3 rollup 1? What have you guys experience with SP2 and or SP3 rollup 1? Any comments would be greatly appreciated. Thanks.

SP3 of course. I would never go to SP2 and than SP3. Since 2007 all the SP's and RU's are Cummulative. Cheers,Gulab | MCITP: Exchange 2010-2007 | Lync Server 2010 | Windows Server 2008 | Skype: Exchange.Ranger | Blog: www.ExchangeRanger.Blogspot.com

Any pros/cons that you have seen with Exchange 2007 SP3 rollup 1? Thanks.

Well I haven't seen one! You should install RU3v2 for SP3 not the RU1 http://www.microsoft.com/download/en/details.aspx?id=9832 Cheers,Gulab | MCITP: Exchange 2010-2007 | Lync Server 2010 | Windows Server 2008 | Skype: Exchange.Ranger | Blog: www.ExchangeRanger.Blogspot.com

I agree with Gulab that you absolutly should install Exchange 2007 SP3. The latest Rollup for that version is RU4 and I would go for that one. Update Rollup 4 for Exchange Server 2007 Service Pack 3 http://support.microsoft.com/kb/2509911 Martina Miskovic

We also have an Edge. Do we also have to update that as well? Thanks.
