Migrate to
MySQL

MySQL is the most widely deployed relational database, and it now ships a native JSON column for anything that doesn't flatten cleanly. NoSQLSync converts your source schema to MySQL types, batch-inserts the historical data, and tails changes in real time.

Migrating to MySQL — FAQ

How long does a migration take?

A typical 100 GB dataset migrates in under 2 hours with bulk mode. With CDC enabled, ongoing writes sync in real time. Total time depends on data volume and network throughput.

Is my data secure during migration?

Yes. All data is encrypted in transit (TLS 1.3) and at rest (AES-256). Database credentials use short-lived tokens. Migration workers run in an isolated environment and never store data after the job completes.

Can I roll back if something goes wrong?

Yes. NoSQLSync only reads from your source — it is never modified, and CDC keeps running until you stop it. If you hit a problem after cutover, point your application's connection string back at the source.
