Cold copy database on ASM. Please advise

Configuration is:
HP Itanium

I have a 4TB database. Application needs to test three scenarios.
Every test should use the same sets of data. So I have been asked to copy the 4TB database to a different diskgroup on the same ASM instance.
Startup the database using the just copied datafiles/controlfiles/redologs.
Then application would run some tests.
Then I should remove the database copy and repeat the steps for creating a new copy from the original 4TB database.

I need to find an efficient way for copying the 4TB database to the new diskgroup on the same ASM.

I cannot use the flashback database option.
The 4TB database can be shut down during the copy.
Storage is fast

My idea is to copy datafiles/controlfiles/redolog using the asmcmd cp command and then renaming datafiles/redologs.

I am not sure if running the copy in parallel is better then copying datafiles one by one.
I could also use the rman backup as copy but I suppose the the result would not be different in term of time taken.

Any suggestion ?

Thanks, massi
