My domain and forest functional level is currently 2003, I am looking to up it to 2008. Both of our Domain controllers are 2008 R2, Exchange 2010 runs under 2008 R2 as does our SQL server, we have a couple of 2003 servers that run older apps and a mixed user base of xp/windows 7 users.<br />
<br />
I'm hesitant to upgrade the level as its something i have never done before and would be concerned in case it broke something.<br />
<br />
any one ever had any problems with doing an upgrade and what problems would I likely to run to ?<br />
<br />
Thank you
