Hi Guys,
We are planning to upgrade the AD server from windows 2008 R2 to windows 2012 and also upgrade AD forest functional level to 2008 R2. We need to know the compatibility of CRM 4.0 with forest functional level windows server 2008 R2. If there is no impact then, is there any changes need to be done in CRM server as well since we have not planned any changes in CRM server. Please help us with any Microsoft links or suggestions.
