Phase 1: Plan Your Migration

Communications Server 2007 R2

Topic Last Modified: 2009-05-15

Migration from Office Communications Server 2007 Standard Edition, Enterprise Edition in a consolidated configuration, and Enterprise Edition in an expanded configuration, either with or without Edge Servers, is supported.

To plan the overall migration to Office Communications Server 2007 R2, you should do the following:

  • Review the Migration documentation in full so that you will understand the migration process.
  • Ensure that your hardware and software meet the requirements for Office Communications Server 2007 R2, which are different from those of earlier product versions. For details, see Software and Hardware Requirements.
  • Prepare for coexistence issues. If you will need for your Office Communications Server 2007 R2 deployment to interoperate with an existing Office Communications Server 2007 deployment, or if you will be rolling out your migration in stages, see Supported Migration Paths and Coexistence Scenarios in the Supported Topologies and Infrastructure Requirements documentation. For other coexistence issues, see Coexistence Issues.
  • Plan user migration and client software upgrades. For details, see User Migration and Client Migration.
  • Plan administrative tool deployment. For details, see Administrative Tools.

These tasks will help you create an overall migration plan. Additional planning specific to server roles is necessary, and this guide covers such planning at the relevant phase in the process.
