Clone a RAC database to a new RAC server

Question

Hi,
How can clone a RAC database to a new RAC environment ?
I installed Cluster and RDBMS 10g R1 in a new RAC server and I need to copy my database "dbrest" to the new server, my new database must have the same name ("dbrest"). My actual dbrest database is in ASM and I need to use ASM for the new database too.
I don't have any database in the new RAC environment.
At the end I need to have this configuration:
Source configuration:
SERVER:
Node 1: srvprod1
Node 2: srvprod2
CLUSTER DB: dbrest using ASM
Node 1: dbrest1
Node 2: dbrest2
Clone configuration:
SERVER:
Node 1: dupenv1
Node 2: dupenv2
CLUSTER DB: dbrest using ASM
Node 1: dbrest1
Node 2: dbrest2
How can I do this?

use rman Duplicate Database on srvprod* to dupenv*

When duplicate database can run on both dupenv1 and dupenv2.
use "srvctl" to add database, instance and services (if you have)
Usage: srvctl add database -d <name> -o <oracle_home> [-m <domain_name>] [-p <spfile>] [-A <name|ip>/netmask] [-r {PRIMARY | PHYSICAL_STANDBY | LOGICAL_STANDBY}] [-s <start_options>] [-n <db_name>] [-y {AUTOMATIC | MANUAL}]
Usage: srvctl add instance -d <name> -i <inst_name> -n <node_name>
Usage: srvctl add service -d <name> -s <service_name> -r "<preferred_list>" [-a "<available_list>"] [-P <TAF_policy>]
Usage: srvctl add service -d <name> -s <service_name> -u {-r "<new_pref_inst>" | -a "<new_avail_inst>"}
