With the first release of an update for Skype for Business Server 2015, it is a good opportunity to publish a list of Cumulative Updates. We will try to keep it updated as soon as a new Cumulative Update is released.
Like in the previous versions, this list will include the version for the Core Components. This is because not all components are updated when we apply a Cumulative Update.
The previous lists for the Lync Server can be found in the following links:
Lync Server 2010 Cumulative Update List
Lync Server 2013 Cumulative Update List
We already made a post on how to check the component version using PowerShell:
Skype for Business Server 2015 Component Version using PowerShell
Skype for Business Server Component Version using Get-CsServerPatchVersion – Requires version 6.0.9319.102 or above)
The latest updates for Skype for Business Server 2015 and how to update each server role is described here:

Hello David,
Do you know, are there any known issues for installing CU12 (Aug 2021) on SfB server 2015?
I’ve done some research for couldn’t find much info.
Thanks
Raj
Far as I know, only this one:

Hello David,
Thanks for sharing your experience, much appreciated. Like your blogs !
Question please.. Once I have updated CU 12 HF2 onto SfB 2015 servers (build 6.0.9319.634), do I need to run below command?
Install-CsDatabase -Update -ConfiguredDatabases -SqlServerFqdn mySQLDatabasenamewithFullyQualifiedDomainName -Verbose
With the current build when I run below command,
Test-CsDatabase -ConfiguredDatabases -SqlServerFqdn “mySQLDatabasenamewithFullyQualifiedDomainName” | Select SqlServerFqdn, SqlInstanceName, DatabaseName, InstalledVersion, ExpectedVersion | ft -AutoSize
it shows same version under “InstalledVersion” and “ExpectedVersion”. After updating CU12 HF2, not sure if “InstalledVersion” and “ExpectedVersion” will still show the same version or not. But basically, want to know whenever you apply any CU, do you require to manually run Install-CsDatabase -Update -ConfiguredDatabases -SqlServerFqdn command at the end?
Thanks,
Raj
Hi Raj, yes in an Enterprise Pool you need to run Install-CsDatabase -Update -ConfiguredDatabases after an update just to make sure any database schema change is also updated.
Since SfB Server 2015 is in extended support it is not expected to have major updates to the database schema.
Thanks David !
Hello Again David, how can I confirm latest update for SfB 2015 is CU12 HF2?
Official Microsoft link only suggests, CU12 HF1, then two security updates in April 2022 and July 2022. Is there any (official) reference on MS website which suggests it is HF2?

Thanks again.
By the way, the new build number is 6.0.9319.634 (up from April’s 6.0.9319.628).
Thank you Raj, I just add it to the table.
