Now that looked at the planning for upgrading to Skype for Business, let’s do the actual upgrade of a Lync Server 2013 topology.
In this post we will make an offline upgrade, meaning that we will take the existing frontend pool offline, and do an in-place upgrade of the frontend server.
Before you start the upgrade process you need to update the Lync servers to the latest CU
And for Windows Server 2012 R2, you also need to install this hotfix.
First you need to mount the SfB Server ISO on a server that don’t have any Lync or Skype components install (ocscore)
Run setup.exe to install the deployment tools.
Read the EULA and Accept it to continue
When the Deployment Wizard is installed and started – install the Administration Tools
When it finish, close the Deployment Wizard and start the topology builder
Click OK to download the topology
Type a name for the topology file and click Save
Navigate to your frontend pool and right click and select “Upgrade to Skype for Business Server 2015″
The Frontend server is now moved to Skype For Business Server 2015.
Right Click and Publish the topology
Click Finish and close the Topology builder.
Wait for replication to finish
Next on the frontend server, start powershell and run this command
This will prevent the Lync services to start should the server be rebooted.
Run the same command on all Lync servers in the pool, that is going to be upgraded.
Next mount the SfB DVD on the frontend server and start setup.exe
Read the EULA ones again and click OK.
After an hour or so the update to finish on the frontend server
Next go to powershell (remember to open the management shell) and start the pool with the below command
Start-CsPool –PoolFqdn fe01.exchangepro.dk
Type Y to start it
The upgrade of the frontend pool is now completed, and you can continue with the other Lync servers that you have in your pool, like the edge and mediation servers.
In the next post we will look at upgrading the Edge, Mediation and Director servers.
