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;
