If you're using migrate-mongo and considering a switch, the biggest concern usually isn't features.
It's this:
"Will I have to re-run old migrations or risk production data?"
The short answer is no.
I built mongo-migrate-kit with migration adoption as a first class feature because switching migration tools shouldn't feel risky.
The Problem
Most teams already have months or years of migration history.
Re-running old migrations is dangerous.
Editing migration records manually is even worse.
What you really want is a way to tell the new tool:
"These migrations already ran. Start tracking them and leave everything else alone."
That's exactly what mongo-migrate-kit does.
Import Existing migrate-mongo History
First, install the package:
npm install mongo-migrate-kit mongodb
Preview the import:
npx mmk import --dry-run
This reads your existing migrate-mongo changelog and shows what will be imported.
Nothing is written to the database.
Once you're happy with the output:
npx mmk import
The migration history is copied into mongo-migrate-kit's tracking collection.
Your original migrate-mongo changelog remains untouched.
What Happens Next?
After importing:
npx mmk status
Previously applied migrations appear as applied.
Any migration files that haven't run yet remain pending.
When you run:
npx mmk up
Only pending migrations execute.
Old migrations are never re-run.
Why I Built This
I originally created mongo-migrate-kit after running into rollback issues during a deployment.
While using migrate-mongo, I found myself wanting more control over migration safety and deployment workflows.
That led to features such as:
- Rollback specific migrations or batches
- Dry-run support
- SHA-256 checksum validation
- Distributed migration locking
- Redo support
- TypeScript support
- Safe migration adoption from migrate-mongo

Final Thoughts
Migration tools should make deployments safer, not add anxiety.
If you're looking for a migrate-mongo alternative or need a MongoDB migration tool for Node.js that can adopt existing migration history safely, give mongo-migrate-kit a try.
