I'm setting up 2 new database servers that will be replacing a current master-slave setup. All boxes are running / will be running MySQL on RHEL.

Our current naming conventions:

db1 - master database

db2 - slave (using MySQL replication)

db01 - new master

db02 - new slave

We need to get db01 to be the new master with db02 as the new slave. What is the best way to migrate db1 and db2 to db01 and db02?

db1 and db2 are running in a production setting and we need to minimize all downtime; db1 has roughly 30GB of data in the database.

Any suggestions or tips on how to migrate to our new servers would be much appreciated.
