need to copy all directories and files from FRA to FRA_NEW disk group

Oracle RAC DB: 11.2.0.3

OS: Red Hat Linux 6

nodes: 2

for a testing purpose I have two FRA diskgroups, FRA and FRA_NEW.

The original FRA have the following 3 directories and various files.

ARCHIVELOG/

CONTROLFILE/

ONLINELOG/

Question: Is there a easy way to copy all directories and their contents(all files) from FRA disk group  to FRA_NEW disk group?

Presently, I had to do the following for each files. note: I had lot more files then below.

cp +FRA/testdb/archivelog/2014_05_29/thread_1_seq_674.680.848829423 +FRA_NEW/TESTDB/archivelog/2014_05_29/thread_1_seq_674.680

cp +FRA/testdb/CONTROLFILE/Current.256.840388675 +FRA_NEW/testdb/CONTROLFILE/Current

cp +fra/testdb/onlinelog/group_1.257.840388675 +fra_new/testdb/onlinelog/group_1.257
