STEP 2: Installing CU5

Download and install CU5

https://www.microsoft.com/en-us/download/details.aspx?id=36820

After the restart we will apply the update of the databases which in my case is going to be the FQDN of the FE server since it's standard version and not Backend server.

Install-CsDatabase -ConfiguredDatabases -SqlServerFqdn lyncfe01.adeo.local -Verbose

Time to upgrade the Archiving/Monitoring databases.

To upgrade we'll use the same command except change the FQDN of the SQL server to the SQL server where Monitoring and Archiving databases are at.

Install-CsDatabase -ConfiguredDatabases -SqlServerFqdn sql01.adeo.local -Verbose

Applying CMS upgrade

Install-CsDatabase -CentralmanagementDatabase -SqlServerFqdn Lyncfe01.adeo.local -SqlInstanceName rtc -verbose

Then run enable-cstopology

Last thing in the CU5 update is

%ProgramFiles%\Microsoft Lync Server 2013\Deployment\Bootstrapper.exe

Step 3 : Installing Windows OS hotfix.

KB2982006 Windows Server 2012 R2

Since the FE is on Windows Server 2012 R2 then we'll need to download this link

https://onedrive.live.com/redir?resid=82488EABA4ACDB15!38654&authkey=!AE9IJKbMPtkge8U&ithint=file%2cexe

RESTART is Required

STEP 4 : Install SQL Service Pack 2 (Express) for your Lync Front end Standard Edition

First Download SQL Express SP2 setup

You can patch the server by opening a Lync Management Shell window and entering the following commands:

Stop-CsWindowsService

.\SQLEXPR_x64_ENU.exe /ACTION=Patch /allinstances /IAcceptSQLServerLicenseTerms

Step 5: SQL Server (Standard or Enterprise) for (Monitoring, Archiving)

https://support.microsoft.com/en-us/kb/321185

My SQL Server version is SP1 so I don't need to upgrade it to SP2

Step 6- In-place Upgrade for Skype For Business

In order to do the in-place upgrade, we'll need to use a machine that doesn't have Lync 2013 to install the new Topology builder and do the upgrade process

On a different Machine that's joined to the same domain, I will run the prerequisites script and restart the machine. then I'll load the Skype for business ISO and install

D:\Setup\amd64\Setup.exe

We'll now press on Installing Administrative tools

Now in order to continue we'll have to open the topology builder in order to upgrade our Lync 2013 topology

I'll open the topology builder and save the topology file somewhere

Once the topology is open, I'll navigate to the Standard FE Servers and right click on my main server to upgrade

I'll click on Upgrade to Skype for Business Server 2015…

As soon as you press Yes, the Frontend server that you selected will be moved under the Skype For Business Server 2015 tab as you can see below.

Since I have two FE servers (FE and SBS) I will be upgrading them both but not in the same time not not fall into any errors, so I will publish the topology and see what happens.

We'll check what do we need to do now in order to upgrade the servers, here is what we'll do.

Import existing normalization rules from the previous Skype for Business Server deployment. If you want to keep your existing normalization rules you will need to import them using the Import-CsCompanyPhoneNormalizationRules cmdlet. If you have separate normalization rules for each pool then you will need to run the command for each set.

To perform an in-place upgrade of your Skype for Business Server, you'll need to do the following, in order:

(1) Stop the Skype for Business services on all of the servers that you are upgrading;

(2) Run Skype for Business Server setup (Setup.exe) on all of the servers you are upgrading;

(3) Start the Skype for Business services on all of the servers you upgraded. To start the services in a Front End pool, connect to one of the servers in the pool and run the Start-CsPool cmdlet. All the servers in the pool should be running Skype for Business Server before you use the Start-CsPool cmdlet. To start the services in all other pools (e.g. Edge pool, Mediation pool), run the Start-CsWindowsService cmdlet on every server in the pool;

Server FQDN: lyncfe01.adeo.local, Pool FQDN: lyncfe01.adeo.local

On Lync FE 01 I'll stop all the services using Stop-cswindowsservice
