13 Database Management : 13.2 Moving an Existing Database into a New Cluster : 13.2.1 Using Migration Toolkit to Migrate to an Ark Cluster

Migration Toolkit is a powerful command-line tool that offers granular control of the migration process. Migration Toolkit can migrate immediately and directly into a Postgres database (online migration), or you can also choose to generate scripts to use at a later time to recreate object definitions in a Postgres database (offline migration).
If you are only migrating schema objects to a cluster, and use an ssh tunnel (with compression enabled), online migration of database object definitions may be a viable option. If you are migrating large amounts of data, network overhead may make an online migration prohibitively slow; Migration Toolkit's ‑offlineMigration option might provide a better migration path.
