I have Lync 2010 SE installed on a Server 2008R2 machine. I need step by step instructions on how to migrate to Lync 2013 EE running on Server 2012 R2. My entire Lync infrastructure is installed on the Lync 2010 server. There's only one box. There isn't a separate Front End or Edge server. SQL Lite is installed on the same server as well. The DB isn't on a separate SQL server.
