CDC here shortens cutover. It is not a replica.

Conversion Studio can run Change Data Capture on PostgreSQL, MySQL, SQL Server, and MongoDB. The UI labels that path zero-downtime. Defaults: snapshot first, slot name migratrix_cdc, change batch 500, poll every 1,000 ms, at most three change passes. Teardown-on-complete is off unless you enable it.

Oracle and Snowflake migrations are one-time full loads. If you need a permanent streaming pipeline between systems, use a dedicated CDC platform. Migratrix CDC exists to shrink a migration window, then stop.
