OCS 2007 Standard migration to Lync 2010 RRS feed

  • Question

  • 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.

  • The migration process from OCS 2007 (aka R1) to Lync 2010 is very similar to OCS 2007 R2 to Lync 2010.  You can follow the same migration steps, but ignore any of the R2-specific migration processes (i.e. Moving Dial-in Conferencing Numbers).

  • Please post the latest Cumulative update URL for OCS 2007 Standard R1.  I know I need to apply the latest updates to OCS before migrating to Lync.  Also, if I apply this update, do the OCS clients need to be updated as well or can they keep the same version for now since they ultimately will be migrated to Lync?

  • I am seeing conflicting information in regards to migration from OCS 2007 R1 to Lync 2010.  Some people say you must goto OCS 2007 R2 first including the schema update before you can migration to Lync 2010.  Above Phil Sharp says you can go from OCS 2007 R1 directly to Lync 2010.  Is that for sure true?

  • Hi,

    you can directly migrate from OCS 2007 R1 to Lync 2010 but not 2013.

  • This is OCS 2007 NOT OCS 2007 R2

    I have installed Lync 2010 and merged the topology.  I am getting "presence unknown" between OCS 2007 and Lync 2010 clients.  All I need is presence and IM working between OCS 2007 and Lync clients until we cutover all OCS users to Lync 2010. 

    Do I have to do any type of federation between the two?

    Is presence and IM even possible between the two?
