Explanation

By using Database Migration Service with a conversion workspace, you get built-in schema and PL/SQL-to-PL/pgSQL code conversion plus a migration job that handles both the one-time backfill and ongoing change-data-capture. That lets you migrate your stored procedures automatically and keep source and target in sync until cut-over, minimizing effort and downtime.
