Do not forget and update the Lync backend databases. ;) We need to patch all the databases, and the LIS / XDS from CMS. First we remember, the Standard Edition has its own local SQL Server containing all databases necessary for its related Frontend Services, therefore a single command similar as for the SQL Backends is required. If you have an Enterprise setup, you need to identify which features are installed, e.g. only native or incl. Archiving/ Monitoring, or even Persistent Chat. This separated databases require their own commands. For the entire process based on Enterprise Deployment, please enumerate your Topology and identify the configured components.

If you are running the second step in upgrading Lync Server 2013 CU1: Install-CsDatabase -ConfiguredDatabases -SqlServerFqdn SE.FQDN -Verbose You might run into an error: Error: An error occurred: "Microsoft.Rtc.Management.Deployment.DeploymentExecption" "Cannot find any suitable disks for database files. You must manually specify database paths." Solution: This error is simply a problem with your disk space. You only need to make sure you have sufficient disk space left. As far as I figured out, you need at least 20GB left on your HDD.   Author: Thomas Pött Managing Consultant Microsoft UC

Beside some Client Updates also the Server components are updated and some issues were addressed. Caution: if you are updating the Lync 2013 Server installation and you have Database Mirroring installed, you need to break the mirror and initiate the update, afterwards you have to reestablish the mirror again: Get-CsDatabaseMirrorState -PoolFqdn Pool.FQDN -Verbose Uninstall-CsMirrorDatabase -DatabaseType Application -SqlServerFQDN EEBE.FQDN -SqlInstanceName SQLInstanceName -DropExistingDatabasesOnMirror -Verbose Install-CsDatabase -ConfiguredDatabases -SqlServerFqdn EEBE.Fqdn -Verbose Install-CsMirrorDatabase -DatabaseType Application -SqlServerFQDN EEBE.Fqdn -SqlInstanceName SQLInstanceName -FileShare MirrorFileshare -Verbose Get-CsDatabaseMirrorState -PoolFqdn Pool.FQDN -Verbose Cumulative Updates & Administrative Tools Lync Server 2013, February 2013 CU1 Lync Server 2013 Resource Kit Tools Lync Server 2013 Debugging Tools Lync Server 2013 Whiteboard...
