[Update] – Upgrade to Skype for Business 2015 Step by Step Guide.

If you are on Lync 2013, Kudos! Microsoft’s V.Next UC line up, already named as ‘Skype for Business’ deployment now features an In-place upgrade path!

Lync Server 2013, compared to Lync Server 2010 had many architectural and backend differences. This led all Lync 2010 admins with only one option, go for a Migration; provision brand new servers, deploy Lync 2013 servers side by side, enable interoperability between the new Lync 2013 and Lync 2010 in a coexisting environment.

The major downside here was the fact that you need to have new hardware provisioned, and that came with a cost! Larger your environment, less likely your budget will get approved. Worst case, you are going to end up with lot of un-used hardware as well after decommissioning the 2010 environment. However, the features and benefits of Lync 2013 always went way higher comparing the cost.

Lync vNext, Skype for Business now supports In-Place Upgrade. Meaning, if you have a Lync Server 2013 environment, you can use the existing hardware to upgrade into Skype for Business 2015. The in-place upgrade also ensures that your environment goes through a smoother upgrade process with minimum effort.

Ok so life’s good for everyone with Lync 2013, but what about Lync 2010? Let’s see what options you have in terms of moving from Lync to S4B.

Existing Environment In place upgrade supported? Migration supported? Service/User downtime required?
Lync 2010 No Yes No
Lync 2013 Yes Yes Required for in-place upgrade scenario
Lync 2013 + 2010 coexisting Yes, Lync 2013 to S4B upgrade (Step 02) Yes, Lync 2010 > 2013 migration (Step 01) Required for in-place upgrade scenario

Lync to S4B transition can be performed in two ways;

  • Migrate users mode (no downtime for users) – Users will be moved across pools or 2010/2013 to S4B pool while keeping all services running and therefore no downtime or impact for users.
  • Offline mode (downtime required for users) – In scenarios where am in-place upgrade is to be performed, the services on the server that will be upgraded needs to be stopped and therefore user downtime will be required until upgrade is completed.
