Win2003 to Win2008 R2 transition fallback plan

-

hi guys,

we have win2003r2 domain controllers(x86) going bring in new win2008r2 dcs , transition over.  2 key steps seem prepping infrastructure adprep commands , then raising forest functional level once running on win2008r2.  know stuff should go smooth, worry if catastrophic happen when performed either of steps.  not know how undo steps without falling backup.

i thinking shutdown dc without fsmo roles before running ad prep command.  if had catastrophic happen not fix in day or so, shutdown of out other domain controllers , bring online old domain controller, seize fsmo roles, , delete other srv records in dns.  know sounds pretty crazy , have of our systems authenticating through single site, take less time trying restore systemstate on domain controllers way before each of steps.  have other simpler ideas?

the option take system state backup prior upgrading schema or raising functional level. raising of dfl/ffl irreversible process. best option create replicate of live environment lab, test & go ahead.

 

question

is there way isolate dc in order ad schema upgrade? cannot find documentation on how this.
