Upgrading OCS 2007 R2 to Lync 2010 – Part 3

Here is the concluding part of the OCS to Lync migration video series. You can find Part1, Part2 as well as other great stuff on the homepage…

In this last part we will:

• Create / move DNS entries to Lync
• Migrate users to Lync Pool
• Finish topology merge
• Upgrade clients to Lync
• Decommission OCS server

For the official documentation on the correct order to decomission and uninstall OCS servers see these technet links:

Removing Servers and Server Roles

Deactivating Server Roles for a Standard Edition Server or an Enterprise Pool

I hope you got some value out of my videos so far, let me know if there’s something else you’d like to see covered or how your OCS to Lync projects go…

Thanks and good luck

Ben.
