The topics in this section guide you through the process of upgrading Microsoft Office Communications Server 2007 R2 Evaluation Edition to the full version of Office Communications Server 2007 R2. These topics have the following scope and criteria:

• Migration from Office Communications Server 2007 R2 Evaluation Edition is supported only for the volume editions of Office Communications Server 2007 R2.
  
  
• Migration from the Evaluation Edition is supported for the following Office Communications Server roles:
  
  
  • Standard Edition server
    
    
  • Enterprise pool
    
    
  • Edge Servers
    
    
• Upgrading the following server roles and tools is not required. These server roles and components do not require a product key for installation and therefore are not subject to the evaluation expiry limits:
  
  
  • Mediation Server
    
    
  • Archiving Server
    
    
  • Monitoring Server
    
    
  • Communicator Web Access
    
    
  • Group Chat Server
    
    

You must upgrade all servers that are running the Evaluation Edition of the following server roles:

• Enterprise pools, Standard Edition servers, or both
  
  
• Directors
  
  
• Edge Servers
  
  

The recommended upgrade sequence is as follows:

1. Internal servers: Enterprise pool, Standard Edition Server and Directors
   
   
2. Edge Servers
   
   

If you are upgrading from any Evaluation Edition server role to the full version of the same server role, you can perform the upgrade in place by running the Windows Installer file Server.msi that is included with the full version. Server.msi will update your installation and preserve any configuration data and existing databases on either a Standard Edition or an Enterprise Edition server.
