Duplicate production RAC to a staging/test RAC

hi,

Just wondering if anyone had any insights/tips/pitfalls regarding how to duplicate a database from a production RAC environment to a testing RAC environment.

I need a way to make a complete copy of a database in a 3 node RAC and put it into a 2 node RAC on completely different hardware - we give the developers and testing groups a complete copy of production to play with. Today it's all standalone instances but shortly I will need to migrate these environments to the new RAC environments.

thanks
