To plan your upgrade to Office Communications Server 2007 R2, do the following:

- 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 Migration Software and Hardware Requirements.
- Understand coexistence issues. Coexistence refers to having both the Live Communications Server and Office Communications Server 2007 R2 operational in the same organization at the same time. For details, see Understanding Coexistence. For additional details, see 支援的移轉路徑和並存案例 in the Supported Topologies and Infrastructure Requirements documentation.
- Plan user migration and client software upgrades. For details, see User Migration from Live Communications Server 2005 and Client Migration from Live Communications Server 2005.
- Plan your administrative tool deployment. For details, see Administrative Tools for Migration from Live Communications Server 2005.
These tasks help you create an overall migration plan. Additional planning that is specific to server roles is necessary too. This guide covers server-specific planning at the relevant phase in the process.
Migration of Live Communications Server Standard Edition or Live Communications Server Enterprise Edition, either with or without Access Proxy servers, is supported.
