Upgrading to a SQL Server 2000 Failover Cluster

SQL Server 2000

When you are upgrading to a Microsoft® SQL Server™ 2000 failover cluster, only one default instance is allowed. Use the Cluster Wizard in SQL Server version 6.5 or SQL Server 7.0 to uncluster any existing SQL Server 6.5 or SQL Server 7.0 clustered instances before upgrading to SQL Server 2000. Then run SQL Server Setup on SQL Server 2000.

SQL Server 6.5 or SQL Server 7.0 failover clusters cannot exist on the same computer as a SQL Server 2000 failover cluster. In SQL Server 6.5 or SQL Server 7.0, in an active/active configuration or in an active/passive configuration where one server contains an unclustered SQL Server, there is a name conflict. Both servers are default instances.

Important  You cannot run the Cluster Wizard in SQL Server 6.5 or SQL Server 7.0 after SQL Server 2000 has been installed.

For SQL Server 2000, you must use a domain account for the services (SQL Server, SQL Server Agent, and all services in the clustered group). That account must be an administrator on all computers in the cluster, if those computers are running on Microsoft Windows NT® Server 4.0, Enterprise Edition.

Note  If you are using replication on a SQL Server 6.5 or 7.0 failover cluster and upgrading to a SQL Server 2000 failover cluster, you must uncluster the previous installation. Delete all publications, remove replication, and then reconfigure replication after upgrading. This will not be a requirement when upgrading from SQL Server 2000 in future releases.
