Prerequisite for Cross-Platform PDB Move
Perform these steps to move a PDB cross-platform from source release 19.19 RU (Linux x86-64 and Microsoft Windows x64) to target release 19.19 Linux for Arm (aarch64).
Before you unplug your PDB from the source container, run these queries to clear the datapatch inventory:
/* Delete all rows from datapatch tables to clear the inventory */
alter session set container=pdb_name;
delete from dba_registry_sqlpatch;
delete from dba_registry_sqlpatch_ru_info;
commit;
