You should follow MOS notes.. We have both Application Tier migration and Database Tier migration documents in MOS..

You should prepare the target nodes ( install RPMs, configure the OS to support EBS and its database)
If the new platform is the same with the source (in terms of arch..) , then the migration approach is super clear.

You will prepare the Database env on target and use some method (for instance Dataguard) to migrate the database to the new platform.. (Single to RAC, RAC to RAC, any kind of db migration can be done.. These things are documented..)

For the apps tier, you shutdown the source apps services, copy the apps directories to target and run post clone on target basically..

However; there are details.. Please see MOS.
