Phase 6: Deprecate Your Live Communications Server 2005 SP1 Servers

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

When you have moved all your users to Office Communications Server 2007 Standard Edition servers and Enterprise pools, you can deactivate and uninstall Live Communications Server 2005 with SP1 and use those computers for another purpose.
