Hy friends!

Help me, please!

Scenario: Migration from OCS 2007 RTM to OCS 2007 R2

Target: Keep user contact list (I'm talking about only OCS contact list from internal organization users, I'm not refer about external addresses)

Question: I want to know if when I move a user from OCS 2007 RTM to OCS 2007 R2 the user contact list is also migrated?

If Yes, can you share the Microsoft documentation that describe it?

So, after I migrate the users to OCS 2007 R2, finally I can do a supported migration to Lync Server 2013. 

Thanks in advance.

If you do a side-by-side migration the contact lists (and other user data) should remain intact. If you tear down OCS2007 and then install OCS2007R2, then you will need to use dbimpexp.exe to export the contact list from OCS2007.

Here is an overview: http://blogs.technet.com/b/ucedsg/archive/2009/02/07/how-do-i-get-from-ocs-rtm-r1-to-ocs-r2.aspx

Also take a look at the deployment guide: https://www.microsoft.com/en-us/download/details.aspx?id=19984 specifically the section called "Updating from Office Communications Server 2007" which lists some potential issues.

Thank you so much Georg!
