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.

Click Install

Read the EULA and Accept it to continue

When the Deployment Wizard is installed and started – install the Administration Tools

Click Next

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″

Click Yes

The Frontend server is now moved to Skype For Business Server 2015.

Right Click and Publish the topology

Click Next

Click Finish and close the Topology builder.

Wait for replication to finish

Next on the frontend server, start powershell and run this command

Disable-CsComputer –Scorch

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

Click Next

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.
