Removing OCS deployment after migration to Lync

Something I have had to do on a regular enough basis to want to post about but irregular enough that I don’t remember…
So here it is.

  1. Log onto OCS server and ensure that all users have been migrated
  2. Ensure all Conference Directories are empty and have been migrated to Lync
  3. From the Lync server – Use the Get-CsConferenceDirectory command in the Lync Management Shell to find the conference directory on the pool you want to remove. There will be a number in the Identity field, and that’s what you need for the next command.
  4. Use the Remove-CsConferenceDirectory -Identity (number from step 3 result) -Force command. If you don’t use the force parameter, it will give you an error if the directory isn’t empty. You will be prompted to confirm your choice whether you use Force or not. Simply enter a Y or A to finish executing the command.
  5. Stop all OCS Services
  6. Deactivate Server Roles
    These server roles should be deactivated in the following sequence:
        • A/V Conferencing ServerA/V Conferencing Server
        • Web Conferencing Server
        • Web Components Server
        • Front End Server
  7. Uninstall the OCS Components, be sure to uninstall all the non-essential bits first. Rule of thumb – do the bits that don’t warn first. Followed by the rest (Exclude the API stuff until last!)
  8. Verify that All OCS component are removed
  9. Log on to Lync, run Topology builder and then remove the BackCompat Site

Remember to check all the DNS records have been updated to the new Lync servers

About Paul B

My name is Paul Bloem and I am employed at Lexel Systems in New Zealand as a Principal Consultant for Unified Communications. I have been working on enterprise voice solutions for over 20 years. My first 10 years were spent working for a Telco in South Africa (Telcom SA). This is where all the groundwork happened as I was exposed to just about every aspect of telecommunication you could imagine. I develop an interest in PBX technologies and eventually became the go-to guy. Next, I had a 10 year run at Siemens South Africa, most of my time there was as a Technical Trainer. During this time VoIP hit the world stage, I had the privilege of introducing VoIP both as H.323 and later SIP across the Siemens HiPath 4000 solution stack. In 2008 I immigrated to New Zealand with my newly attained MCSE, I was ready to go where no PBX Techie had gone before. I was employed to explore OCS 2007 and that was pretty much the beginning of the end for me. I have been working on OCS and Lync ever since. My current role focuses exclusively on Lync and associated technologies.. That includes pre-sales, consulting, architecture and design, training and support. I even get to play in the development space from time to time - focus on play ;-) I was nominated as a Microsoft VTSP for Lync early in 2013 and also awarded Microsoft's MVP award for Lync in 2014.
