When you are removing the Microsoft Lync Server 2010 deployment, you need to remove database and log files on one or more database servers. You may encounter a scenario where you need to retain the database and log files (for example, a hardware move), or in a different scenario where you need to delete the database and log files (for example, moving from test to production).

Important:
The following procedure notes whether a step might cause irreversible loss of the database files given a particular scenario.

To uninstall SQL Server instances and, databases

  1. Log on to the computer where Lync Server Management Shell is installed as a member of the Domain Admins group or the RTCUniversalServerAdmins group. You must also be a SQL Server sysadmin or equivalent on the SQL Server where the databases are located.

  2. Start the Lync Server Management Shell: Click Start, click All Programs, click Microsoft Lync Server 2010, and then click Lync Server Management Shell.

  3. To drop and retain the database and log files associated with user information (for example, access control lists, home server or pool, and scheduled conferences), type:

    Copy Code 
    Uninstall-CsDatabase -DatabaseType User -Detach -SqlServerFqdn sqlbe.contoso.net[-SqlInstanceName <instance name>]
