  • FSMO roles, Upgrading to 2008 R2

    Hey guys,

    We are going to migrate our 2003 domain to a 2008 domain (thanks god finally, tnew GPOs). I was looking at this: http://www.petri.com/determining_fsmo_role_holders.htm

    DC1 is:

    RID Master
    Infrastructure Master
    PDC Emulator
    Domain Master

    DC2 is:

    Schema Master

    So, my first planning was to move the role to DC1, reinstall the DC2 in 2008, rejoin domain as DC, and put all the role back on this one so I can reinstal DC1 (and also put DHCP on it).

    After looking at it, in GUI mode: I have DC2 and DC2..

    So my guess is that I should use Ntdsutil to move this role to the DC1, before Depromote the DC2?

    Thanks

    Why not just do an in-place upgrade of the domain controllers instead of rebuilding them?

      Working from 2003 32bits to 2008 x64?

          Do consider 2008R2 or 2012 as 2008 is a bit long in the tooth now

            Agreed, for sure look at going to 08R2 or 2010, regular 08, gives you a little extra time if microsoft XP's it.

              Misstyped:

              2008 STD R2 with SP1 x64 this is what we have.

              So, reinstalling I need, I thought maybe server would allow going from 32 to 64.

              Transfering the schema with ntdsutil would be okay? no issue there to have all role on the same server?

                No issues having all the roles on the same server. You plan sounds good to me. Make sure you have good backups before you start.

                  I have a couple of system state backup. I think I should be fine. I will just have to make it join really fast the domain (you know, that would be shitty if while reinstalling, the first one crash haha)

                  Thanks for confirming guys!

                    There's no problem with both DC's being GC's in a single domain forest, so go ahead and make the new server a GC as a first step. If your AD DNS is AD integrated then no "transfer" of DNS is required, the AD DNS zones will be replicated to the new server as part of the AD replication process. The only thing you'll need to manually transfer is DHCP. You can do this beforehand and authorize the new DHCP server but leave the scope deactivated until you're ready to make the switch. I would recommend that you not give the new server the same ip address as the old server as that's likely to make things flaky because of the DNS records tied to the old ip address of the W2K3 DC. Update your DHCP scope to assign the new server as the primary DNS server for the DHCP clients and manually set it for statically assigned hosts. Once you've done that you can turn off DHCP on the old server and activate the DHCP scope on the new server. After verifying that everything works you can DCPROMO the old server to demote it.

                    If you transfer the DHCP database beforehand, the lease information will be out of date by the time the scope is activated. If the OP is intent on a cut-over instead of a split-scope migration, you should do the export and import right before the cut over.

                    Hope it works...

                    Cheers...!!!

                      As an interim measure why not utilise a virtual server, or even an old desktop, which will allow you to have both servers running at the time of upgrade.

                      You can then move things around and get comfortable with your 2008 install prior to upgrading fully.

                        That would have been a good idea. I didn't thought about this.

                        But I took a big breath, transfered all role on DC1, and reinstalled DC2. Went fine.

                        Only when I did DC1, backuped DHCP, transfered roles, all this went fine except I forgot to modify a logon script which caused some issue with users

                        So now, 2 DC in 2008 R2, Domain raised to 2008 R2, RRAS, DHCP came back to DC1. Role are separated on the two server.

                        went easy I think. Next time, maybe a temp server would be a nice idea. I'll keep this info for our Other site that will migrate in a couple of months. Just need to make sure that all the role are transfered. There is something strange event during the migration but all came back okay after.

                        Thanks guys
