Hi,<br />
<br />
we have approximately 10 DCs with server 2003 operating systems and have started introducing 2008 R2 as our OS server replacement. Domain functional level is obviously still 2003. <br />
<br />
i was wondering if you have gone through the domain functional level upgrade project and if so, what approach did you take; what issues/road blocks did you come across during the project?<br />
<br />
Thanks
