SYMPTOMS

Restored Pluggable database in a different container and unplugged. Dropped existing old PDB and trying to plug in new PDB and getting error:
ORA-65122: Pluggable database GUID conflicts with the GUID of an existing container.

SQL> drop pluggable database PDB1 INCLUDING DATAFILES;

Pluggable database dropped.

SQL> SET SERVEROUTPUT ON
DECLARE
compatible CONSTANT VARCHAR2(3) := CASE DBMS_PDB.CHECK_PLUG_COMPATIBILITY(pdb_descr_file => '/tmp/cdbrf_pdb1.xml')
WHEN TRUE THEN
'YES'
ELSE 'NO'
END;
BEGIN
DBMS_OUTPUT.PUT_LINE(compatible);
END;
/SQL>
YES

PL/SQL procedure successfully completed.

SQL> create pluggable database PDB1
using '/tmp/cdbrf_pdb1.xml'
COPY FILE_NAME_CONVERT = ('+DATA', '+EON_DAT_QA');

create pluggable database pdb1

ERROR at line 1:
ORA-65122: Pluggable database GUID conflicts with the GUID of an existing container.

CAUSE

The same PDB had been plugged previously hence the GUID already exists

SOLUTION

This is expected error.

Use AS CLONE clause.

create pluggable database ....
AS CLONE using '.....xml'
file_name_convert=(...,..);

Or, if you would like to move the XML file, you can use:
create pluggable database ....
AS CLONE using '.....xml'
MOVE
file_name_convert=(...,..);

AS CLONE option is used when target CDB already contains a PDB that was created using the same set of data files. And this is the case here.

Please take a look at:
https://docs.oracle.com/database/121/SQLRF/statements_6010.htm#SQLRF55686
"
AS CLONE Clause

Specify this clause only if the target CDB already contains a PDB that was created using the same set of data files. The source files remain as an unplugged PDB and can be used again. Specifying AS CLONE also ensures that Oracle Database generates new identifiers, such as DBID and GUID, for the new PDB.
