Server & Exchange upgrade path
I currently have a server which is running Windows 2000 & Exchange 2003.
I will need to upgrade it to Windows 2008 R2 + Exchange 2007. It's a 12 user site. The Exchange data size is 32gb (yes I know . . . ). What steps would you take upgrade? The new OS will hopefully reside on the same hardware as the current system. Specs: 2 x Dual Xeon 3ghz, 3gb RAM going up to 8gb, 130GB of storage on a RAID 0+1 over 6 disks. |
Exchange 2007 SP2 won't be supported on 2008 server R2. See here for details.
|
ouch, didn't know that
|
Yeah - looks like they are trying to push people straight to Exchange 2010...
|
I guess I'll hold off until release then. . . . any ideas when that is - google revealed nowt.
|
Exchange 2010 release date is October 6th 2009. I was told this yesterday at one of Microsoft's roadmap sessions.
|
not long at all then. By the time I've updated my clients to something sensible. ..
Does this path seem logical: - Take a good backup. - Build a 2008 R2 & EX 2010 on a random PC. - Migrate mailboxes over. - Format the old server & reinstall 2008R2 & Exchange - Migrate the mailboxes back |
Exchange 2010 and 2007 (apart from a few key exceptions) will only install on 64bit hardware. Your Random PC as you call it will have to match this.
Given when you want to do I see this as your only option really. Is the domain hosted on separate DC's? Darren |
The domain is on a separate DC.
Although it's not recommended, I'll have the EX server as a DC as well - as our workload is fairly light it'll be ok. |
As you are rebuilding the server which is a DC then I'd take away any roles it has and then demote it (dcpromo) before formatting. Does it hold any roles?
Having EX2007 on a DC is supported so I'd assume 2010 is as well. Is it suggested to put EX on first and then promote to a DC or Promote and then install EX? I'm planning on upgrading from EX2003 quite soon but can't decide whether to go for 2007 or 2010 but I have to upgrade our entire office suite and cals first and then our DR site. It suddingly turns into a big job. Darren |
likewise.
Just checked the hardware - my CPU's aren't x64 compatible. . .. |
In that case I'd upgrade your clients to Office 2007 (Office 14 is not out for a while yet) and then sit with EX2003 for now and then buy a x64 server and upgrade to 2010 once it's been live for a while.

I thought running Exchange 2007 (and maybe 2003) on a DC was supported but not recommended.
<Goes away to check> |
I could never understand how something that is not recommended is still supported.
It's not ideal but I can understand why people do have a server providing both services. The fact the BLK is running a 2nd DC means he can always demote it if he ever had problems. Darren |
I have a couple of private clients (small offices - 5-10 users) that have one server running AD and Exchange -- both been running fine for 4/5 years
they dont recommend because they are in the business of selling server licenses |
Not recommended, but it's what you get with SBS....

MS do a U-turn...
You Had Me At EHLO... : Supporting Exchange 2007 on Windows Server 2008 R2 Earlier this year we made a decision in one direction, and due to the feedback we have received on this blog and elsewhere, we have reconsidered. In the coming calendar year we will issue an update for Exchange 2007 enabling full support of Windows Server 2008 R2. We heard from many customers that this was important for streamlining their operations and reducing administrative challenges, so we have changed course and will add R2 support. We are still working through the specifics and will let you know once we have more to share on the timing of this update. |
Good news Chris.
|
Indeed. You could hear the screech of brakes and frantatic gear changes looking for reverse from here :D
