Im wondering if i can install LYNC as a test basis side by side by the production OCS 2007 R2.
They would both be in the same domain, but off course on seperate domains.
Reason i ask is because i know LYNC does a schema update, and i wanna make sure this does not conflic with existing OCS
Yes a migration allows both pools to run in the same AD domain at the same time, but I would not recommend installing Lync 2010 in a production AD domain until I had a plan and knew how to deploy it. Test/learn on a different test AD domain.
