Exchange Server 2010 setup cannot continue because there are Exchange 2000 Server servers in the forest.

Exchange 2010 requires that all Exchange servers in the forest be running Exchange Server 2003 or later.

To address this error, upgrade the Exchange 2000 server to Exchange 2003 or later, or remove the Exchange 2000 servers from the forest and then rerun setup.

For more information on upgrading the Exchange 2000 server to Exchange 2003 or later, see the following exchange server resources:
