Upgrading Skype For Business 2015 (Latest CU)

Srinivas M 121 Reputation points


We are planning to update SFB 2015 Enterprise Edition CU of our organization, We have below SFB Setup in place.

6 FE Servers.
2 Backend Servers
2 Director Servers
2 Edge servers.

We are planning to update CU on phase by phase manner considering business criticality. Eg 2 Front End servers each day (5 Days Plan).
we want to know in the above scenario whether my existing setup will work without updating backend database (Install-CsDatabase -Update -ConfiguredDatabases -SqlServerFqdn <SQL Server FQDN> -ExcludeCollocatedStores) because of sql database version differences between CU updated FE servers.

    @Srinivas M ,

    Don’t worry about that. Just make sure that your SQL server is supported by Skype for Business server 2015.

    The following picture shows the supported list(everything is 64-bit edition, you'll notice, please don't use 32-bit editions):

    For more information, please refer to this article.
