Database Updates

Once you have installed the SfB\Lync updates, for each server role you upgraded, you need to install database updates. This is taken care of using the following command, where <Server FQDN> = Std Edition Server/Enterprise Edition Pool SQL Backend/SQL Monitoring Backend/SQL Archiving Backend/PChat Server or SQL Backend/. Some roles may be co-located, and thats OK.
