We currently have OCS 2007 Standard (pre R2). Single server for internal use only. I want to migrate to Lync 2010, then later migrate to Lync 2013. All of the articles show migration from OCS 2007 R2 to Lync 2010/2013. Are there any special steps required to go from OCS 2007 Standard (pre R2) to Lync 2010? Please point me to any suggested articles for a migration path.
