Migration from Live Communications Server 2005

Communications Server 2007 R2

Topic Last Modified: 2009-11-20

The topics in this section guide you through the process of migrating from Microsoft® Live Communications Server 2005 with Service Pack 1 to Microsoft Office Communications Server 2007 R2 and for deploying Office Communications Server 2007 R2 in an existing Live Communications Server 2005 environment. If you intend for your Office Communications Server 2007 R2 deployment to coexist with a Live Communications Server 2005 environment, this guide includes some essential information for operating such a mixed environment.

This guide provides information specific to upgrading your existing Live Communications Server 2005 with Service Pack 1 deployment; it does not explain how to change your existing topology. This guide does not cover the implementation of new features. Because many of the detailed planning and deployment information and procedures are provided in other Office Communications Server 2007 R2 documentation, that information is not duplicated in this guide. When a detailed procedure is documented elsewhere, this guide directs you to the appropriate document or document section.

Migration is one part of deploying your Office Communications Server 2007 R2 environment. You should be aware of how migration fits in the overall planning and deployment process.

For details about planning, including supported topologies for Office Communications Server 2007 R2, see the Office Communications Server 2007 R2 Planning Guide and Office Communications Server 2007 R2 Supportability Guide documentation.

For details about deploying Office Communications Server 2007 R2, see the Deploying Office Communications Server 2007 R2 documentation.
