As someone currently contemplating updating our forest/domain level, I'll say it can be done as we are actively running FSMO roles on a WS08 R2 DC with Forest/Domain levels still at WS03, but your schema might need extending first.
I can only imagine how awful this must be, and I have been told I have a pretty good imagination-hang in there. How many servers did you lose altogether? -Bonnie From: James Hill [mailto:hill.ja...@gmail.com] Sent: Friday, January 14, 2011 1:41 PM To: NT System Admin Issues Subject: Re: So...our data centre is under water Thanks Jim. I didn't want to change the domain level. Wanted to leave it at 2008 but was wondering if the FSMO roles can be installed on a 2008R2 server with the domain level at 2008.

Given all that you have to deal with, I am not sure I would change your domain level at this point.

As a result we lost our data centre, it ended up being completely under water. We managed to save some components thanks to some knee high walking in water before it got too high. A very critical server was later rescued thanks to a boat and some roof removal. Walking in to your Data Centre in knee high water is some what depressing. Seeing the lights on equipment that is higher in the racks(and dry) still being powered by the UPS in a dark room filling up with water is well...uncomforting. We are now in hectic DR mode and are restoring services as quickly as possible. Unfortunately we didn't have a DR location(planning was under way but nothing was in place) and so a lot of the restore means retrieving data from tapes and building servers from scratch. I'm in new territory here and so I'm hoping the list can help me out with some questions that I know will arise as I work through this mess. We have secured space in a nice and dry Data centre and have organised WAN and Internet connectivity(although it's not fired up yet), some rack space, and have rented VM's and disk space. We have a 2008 level domain with a mix of 2008 and 2008 R2 DC's. The two DC's we lost were running 2008 and held the FSMO roles. We have C: drive and system state backups of these. We have a number of other DC's out in our stores that are high and dry. What I would like to do is:- Create a new DC in the new Data Centre with a new name but running 2008R2 (take the opportunity to upgrade it). Give it the FSMO roles (is this possible considering the domain level is at 2008 but the server would be 2008 R2)? Clear out the two lost DC's from AD entirely. Thoughts, suggestions and messages of sympathy are all welcome.
