Migrate Form Stand Alone To Clustered Server

Here is the scenario:
We have an existing production non clustered SQL 2000 server instance that we need to migrate to a new clustered SQL 2000 server instance. We need to accomplish this without affecting the FQDN that applications use to call this server. I found this article on a solution to rename the server after an xcopy of the entire db structure. Here is the link http://vyaskn.tripod.com/moving_sql_server.htm. The other issue that we are trying to resolve is the time it takes for the snapshots of replication to run (in our case almost a full day). That is why this approach looked like it may be a good solution for us.


Here is the question:
Is it possible to move our existing database to a new clustered environment without having to change the FQDN that other applications use to access this database and without having to reinitialize replication?
