Lync 2013: Prepare Current Forest task failed

Environment:

I am installing Lync 2013 in AD where I already have Lync 2010 installed. Lync 2010 security groups are in a dedicated OU.

Issue:

Forest Preparation failed with the following error:

Error: Existing universal groups were found in "OU=Lync,OU=Demo Security Groups,DC=XXX,DC=XXX,DC=XXX,DC=com". Specify where to create new Lync Server universal groups explicitly at the command line with the GroupDomain parameter.

Resolution:

Move Lync security groups to a default “Users” container in AD.

the resolution is found here: http://social.technet.microsoft.com/Forums/zh/ocsplanningdeployment/thread/f3ab494b-fc9e-43ae-8268-411ead5e7317
