This question was posted on the blog a few days ago referring to my previous blog posts describing the two techniques to upgrade in an Oracle Multitenant environment:
Question:
We are planning to upgrade from 12.1.0.2.1 to 12.1.0.2.5. The plan is to create new 12.1.0.2.5 oracle home and gradually moving PDB from 12.1.0.2.1 to 12.1.0.2.5. Should I follow the same steps? Is there any document for what we want to do?
And luckily there is a MOS Note out there describing the steps:
The part this note is not talking about is the unplug/plugin operations in detail.
But this is something you’ll find here:

I have a related question about plugging and un-plugging. WHat is the process for unplugging a PDB from a CDB that has TDE enabled another CDB that also has TDE enabled?
Thanks

I have not the exact note but this one describes the process for a non-cdb to pdb and is applicable as well.
Oracle Support Document 1678525.1 (How to migrate a non pluggable database that uses TDE to pluggable database ?) can be found at: https://support.oracle.com/epmos/faces/DocumentDisplay?id=1678525.1
