Hi,
In release 12.2, we can use database link to clone the PDB. Here is the example.
SQL> CREATE USER c##clone_dba IDENTIFIED BY clone_dba CONTAINER=ALL;
SQL> GRANT CREATE SESSION, CREATE PLUGGABLE DATABASE TO c##clone_dba CONTAINER=ALL;
SQL> CREATE DATABASE LINK clone_link CONNECT TO c##clone_dba IDENTIFIED BY clone_dba USING 'pdb1';
SQL> CREATE PLUGGABLE DATABASE pdb2 FROM pdb1@clone_link;
CON_ID KEY_ID
