Upgrading from server 2000 to server 2008R2?
in [Windows Servers]
|
From: Jazsnap on 28 May 2010 07:05 We would like to upgrade our servers to Windows server 2008 R2. Currently we have two Windows 2000 (SP 4) domain controllers, we want to replace the Forest Root Domain box with new hardware & upgrade the other DC to server 2008 R2. I understand it's not possible to upgrade from 2000 straight to 2008 but is server 2003 still available to ugrade to in between? I'm also not sure of what the implications of retiring the Forest Root Domain box would be? Would the best plan be to add the new 2008 server (domain function & forest function level: 2000); upgrade the second box to Server 2008 R2 (via server 2003?); transfer the roles from the FRD box to the others; demote the FRD to a member server then finally raise the forest & functional levels of the 2 remaining DCs? Any advice would be greatly received? Regards, Jason

The route you propose seems the proper way but I would make the new Win2k8 server a DC and maybe transfer the FSMO roles before upgrading the second box. If during the upgrade something is not ready for a Win2k8 DC it's a bit late finding out. This way you will have a wording Win2k8 DC before upgrading an older DC to Win2k8. Make sure you prepare the AD using the adprep tool. http://technet.microsoft.com/en-us/library/cc731728(WS.10).aspx Bonno Bloksma

From: Hank Arnold on 30 May 2010 08:38 In addition to Meinolf's and Bonno's processes, you need to determine whether or not your current boxes support the OS. IIRC< Windows 2008 R2 *REQUIRES* a 64 bit server. I'm dubious that any server running Windows 2000 meets that requirement.....
