> Schema tool currently supports relocation of database from one catalog to another, one at a time. While having to do this one at a time is painful, it also lacks support for converting them to external tables during migration, in lieu of the changes to the translation layer where a MANAGED table is strictly ACID-only table.
> Hence we also need to convert them to external tables during relocation.
