Ensure that servers running Live Communications Server 2005 have the following updates installed:

These updates are required to provide proper coexistence between Live Communications Server and Office Communications Server 2007 R2. These updates must be installed on all servers running Live Communications Server, including the Back-End Database Server for an Enterprise pool.

For performance reasons, we recommend that you move the Live Communications Server Global Settings to the Configuration container in Active Directory Domain Services (AD DS). You must take this action prior to performing any other Office Communications 2007 R2 installation actions. If you do not take this step now, you will not be able to take it after you begin deploying Office Communications Server 2007 R2. For details, see Migrating Global Settings Containerin the Office Communications Server 2007 R2 Deployment documentation.
