Things to be considered before AD - domain and forest functional level upgrade (win 2003 to 2008 R2)

-

hi

recently introduced windows 2008 r2 dcs , decommissioned old windows 2003 domain controllers. since not sure application compatibility (both ms , 3rd party) many times postponed plan upgrade dfl , ffls. found jonathan's blog (http://blogs.technet.com/b/askds/archive/2011/06/14/what-is-the-impact-of-upgrading-the-domain-or-forest-functional-level.aspx), whcih says upgrade won't affect applications. confirm experts posting concern once again. have exchange 2010 / shrepoint / sql / sap etc..(also 2 x windows 2000 servers)

please let know real experiance - in production environment how upgrade 2003 2008 r2 (belive can able upgarde both ffl , dfls win 2003 win 2008 r2) affects existing applications.

thanks in advance

hi,

before upgrade, recommend remove installed non-windows-delivered software not supported software manufacturer upgrade. otherwise, software may not function correctly after upgrade.
