The platform addresses key challenges including WAL bloat, sequence synchronization, replication slot continuity, and safe cutover mechanics. It uses a hybrid pg_dump + logical replication approach with parallel restore, DDL safeguards via event triggers, and intentional human approval gates at critical decision points. The result is a system where teams can trigger migrations autonomously while DBAs retain strategic oversight, reducing migration time from days or weeks of constant attention to a largely automated process. ## Full article daily.dev links to this article rather than hosting it.
