Is there a way to perform an upgrade of an existing SQL Server 2000 standalone system to a clustered environment without having to run through the install process, redefine the databases, load (re-attach) from backups and somehow load master (for security, system catalogue) ?

The current system is connected to a SAN, but master and other system databases are on local drives,and the user databases are on shared drives.

Is there a migration wizard or interface ? Or is a fresh install(s) required with subsequent database migrations to respective shared disk devices ?
