RMAN restore DB in no archivelog mode to different server with different structure - step verify

 Hello:

I just need to verify that I'm using the correct step to restore (clone) a 'no archivelog mode' database to another server (different os structure) by RMAN; in both ways I shutdown the database.

I used to do it a long time ago; by reading resource on internet, I realized there are 2 different approaches -

(1). RMAN approach:

1-1. take a cold backup of source DB (shutdown DB, startup mount, run full DB backup command in RMAN);

1-2: copy backup pieces to destination server

1-3: start restore at destination: :

1-3-a:edit initSID.ora parameters (adump/cdump/bdump/udump/.. etc)
