DUMP

This strategy is used to migrate "only" the schema (mostly). When migrating from a legacy (Hive 1/2) hive environment to a non-legacy (Hive 3+) hms-mirror will convert tables that are "managed non-transactional" to "external/purge". This translation is a part of the HSMM (Hive Strict Managed Migration) process that run for 'in-place' upgrades.

hms-mirror is mostly designed for "side-car" migrations which involves two separate clusters.
