You might need to reinstall Microsoft Lync Server 2010, Group Chat for various reasons, including updates to the software or a move to new hardware. The user rights, permissions, and ownership of the new installation must be the same as the original installation. An easy way to ensure this is to do the new installation by using the same user and group as the initial installation. Otherwise, change the user rights, permissions, and ownership of the copied directories on the new computer so that they match the user rights, permissions, and ownership of the original directory.

The following sections describe how to reinstall and restore Lync Server 2010, Group Chat.

Migrating the Server Data

Most Group Chat Server data, including user accounts, channel information, and chat history, is stored in the database. Contact your database administrator for information about moving the database.

Caution:
Stop all servers and the Web service before you make changes to the database. Do not reconfigure Group Chat Server during migration of data. Perform any reconfiguration only after the successful migration of data.
