upgrade windows 2008 AD Std svr to R2

I've been running windows 2008 std active directory for a number of years now and I would like to upgrade my AD servers to R2...can I just install R2 on all and then upgrade the functional level to R2??

does seem logical but not sure...thanks for you input.

You could, provided all your installs were Server 2008 x64 (there is no 32 bit version of R2 and there is no 32 bit to 64 bit upgrade path).

HOWEVER, I never have and I never would.  I want STABLE systems and the best way to achieve that is with a clean install of the OS and a migration of AD from the 2008 servers to the 2008 R2 servers.

Are your current boxes 32 or 64 bit.  If they are 64 bit you can but you would have to still update your schema (adprep).  adprep32 if your current box is 32 bit.

If your 2008 system is 32 bit then your only choice is a new box.

Windows 2012 was released last week if you want to go down that path :)


Another vote for clean install. ;)
