You installed a update to your Lync 2013 server and wonder if the database has to be updataed (install-csdatabase….).

Run :

Test-CsDatabase -ConfiguredDatabases -SqlServerFqdn sqlserver.fq.dn | Select DatabaseName, ExpectedVersion, InstalledVersion

Result:
DatabaseName               ExpectedVersion            InstalledVersion
————               —————            —————-
rtcxds                     15.13.1                    15.13.1
rtcshared                  5.0.1                      5.0.1
rtcab                      62.42.2                    62.42.2
rgsconfig                  5.5.1                      5.5.1
rgsdyn                     2.2.1                      2.2.1
cpsdyn                     1.1.2                      1.1.2
xds                        10.13.2                    10.13.1
lis                        3.1.1                      3.1.1
As you can see there are a version conflict. You should update the database.

In this example the Central Management Database is not up to date. Check Microsoft TechNet KB 2809243 for the correct procedure: 

Install-CsDatabase -CentralManagementDatabase -SqlServerFqdn CMS.FQDN -SqlInstanceName DBInstanceName -Verbose
