I have been tasked to migrate our OCS 2007 R2 server to Lync 2013. There are about 200 clients using basic functionality, IM, VM, Conferencing. I am unable to find a step-by-step guide on how to get started. There are hundred of articles but in bits and pieces. I would very much appreciate if someone can point me on how I can get started. It would be nice to get a solution which meets high availability and DR.
Thanks for your help.
