Renaming PDB after clone

Dear Experts,

We are cloning from PROD to UAT. This is the first clone from PROD. We are facing issue while renaming PDB from PRODDB to UATDB. Please need your suggestion to fix this issue.

ENV:
=====

2 node RAC 19c 19.12

Source CDB prodcdb--> prodcdb1 and prodcdb2
Source PDB name PRODDB

Target CDB uatcdb-->uatcdb1 and uatcdb2
Target PDB name UATDB

After completion of RMAN duplicate:
==================================

[orauat@erpuatdb1 ~]$ sqlplus "/as sysdba"
Version 19.17.0.0.0

SQL> sho pdbs

  CON_ID CON_NAME            OPEN MODE RESTRICTED

     2 PDB$SEED            READ ONLY NO
     3 PRODDB             READ WRITE NO

SQL> alter session set container=PRODDB;

SQL> select count(*) from cdb_services c, service$ s
where upper(s.name) = upper('UATDB')
