You just need to do cloning..
Your db will stay in the same node.
Your application tier will migrate to the new node.
So basically, you will copy your apps tier to the new apps machine and then run postclone in the apps tier. ( I recommend you to run exec fnd_conc_clone.setup_clean + db tier autoconfig first)

Note that, if your new machine will have the same hostname and ip address of the old one, then you don't even need to run postclone..

You will do cloning (rapid clone).
Please read the related documents in Oracle Support.
These are well known things.
