Database Migration Services With Low-Downtime Cutover
Database migration services for moving production data between engines and clouds: MongoDB to PostgreSQL, Firebase to Supabase, MySQL to PostgreSQL, or self-hosted to managed. Mapped, scripted, verified row by row, and switched over with a rollback ready.
What We Serve
Move Your Data Once, Correctly, With Proof
A database migration is the one project where almost right is not good enough. A missing row is a missing invoice. A wrong time zone shifts every booking. A changed data type quietly rounds money. Teams put these moves off for years, and the database they wanted to leave keeps getting bigger. Our database migration services make the move predictable. We profile the source data, including the records that break the rules, design the target schema, and write the transformation as code that can run again and again. Old and new are kept in sync while both are compared by counts and checksums, and the application is switched only when the numbers match. The same team updates the application code, so queries, types and tests change together with the data. AI tools draft mappings and scripts; senior engineers review every one.
Our Approach
Profile, Map, Backfill, Sync, Compare, Switch
We profile the source first: sizes, types, nulls, duplicates, orphaned references and the oddities years of production leave behind. The target schema and a field-by-field mapping are agreed in writing. A backfill copies history, then change capture or dual writes keep the new database current. Automated comparisons run until both sides agree, and the application is tested against the new database with production-like load. Cutover is a short, scheduled step with a checklist. The old database is kept in sync in reverse or held read-only for an agreed period, so going back remains possible.
What Is Database Migration?
Database migration is moving data, and the structure that holds it, from one database to another. That can mean a new engine, such as MongoDB to PostgreSQL, a new platform, such as Firebase to Supabase, a new host, or a redesigned schema inside the same engine.
Schema conversion
Tables, types, keys and indexes redesigned for the target.
Data transfer
History copied and live changes kept in sync.
Verification
Counts, checksums and sample checks on both sides.
Application cutover
Queries and code switched with a tested way back.
At Devoq Design, database migration means a mapped, verified and reversible move delivered about 5x faster, with senior engineers reviewing every script.
Why Professional Database Migration Matters
Data is the one part of a product that cannot be rebuilt from scratch. A migration should leave it more trustworthy than it was, not less.
Nothing Lost
Every record accounted for with counts and checksums.
Nothing Changed by Accident
Types, time zones, encodings and precision handled explicitly.
Short Downtime
Live sync reduces the switch to a planned moment.
A Tested Rollback
The old database stays usable until you sign off.
Cleaner Data
Duplicates and orphans fixed on the way across.
A Faster Product
A schema and indexes designed for how the product works now.

Frequently Asked Questions
What do database migration services include?
Profiling the source data, designing the target schema, writing and rehearsing the migration scripts, keeping old and new in sync, verifying the data with counts and checksums, updating application queries, the cutover itself, and a rollback plan. Devoq Design also handles the application and infrastructure changes around the move.
Can you migrate a database with zero downtime?
For most systems the interruption can be reduced to a brief, planned switch, and for some it can be avoided entirely. We copy historical data, keep the new database current with change capture or dual writes, and move traffic once both sides match. The right method depends on the engines involved and how the application writes data.
Why do teams move from MongoDB to PostgreSQL?
Usually because the data turned out to be relational: many lookups between collections, reports that need joins, or a need for stricter constraints and transactions. PostgreSQL handles those natively and still stores JSON for the flexible parts. We review the access patterns first and only recommend the move when it clearly pays off.
What is involved in a Firebase to Supabase migration?
Firestore collections are mapped to PostgreSQL tables, auth users are imported, stored files are copied, and security rules are rewritten as row level security policies. Client code that called Firebase is updated to the Supabase client. We rehearse the move on a copy and keep the Firebase project read-only until you sign off.
How do you make sure no data is lost or changed?
Verification is automated. We compare row counts per table, checksums on batches of rows, totals on important numeric columns and a sample of full records, before and after cutover. Types, time zones, character encodings and decimal precision are mapped explicitly in the mapping document, not left to defaults.
How is this about 5x faster than a traditional agency?
Four things add up: several AI-drafted options at once instead of one at a time, generated boilerplate and tests instead of hand-written setup, reusable component libraries instead of page-by-page builds, and automated checks on every change instead of a manual pass at the end. Review time stays the same; waiting time disappears.
Is AI-assisted work good enough, and is it safe?
AI never ships anything on its own. A senior lead reviews every design and every code change, automated tests and accessibility checks run on each one, and the code is plain TypeScript in your own repository. We do not send your customer data to AI tools without a written agreement.
Who owns the code, the design files and the accounts?
You do, from the first week. Figma, GitHub, CMS and hosting accounts are created under your company, and the contract assigns the IP to you. There is nothing to hand back at the end because it was always yours.
How do you charge: fixed price, monthly retainer or dedicated team?
All three, depending on the shape of the work. A fixed price when the scope is clear, a monthly retainer when the work keeps evolving, and a dedicated designer or engineer pair when you want capacity inside your own team. We recommend one after a short discovery call.
Do you work with companies in the US, UK, Canada or Australia?
Yes, most of our clients are there. Devoq Design has teams in India, Canada and the US, so every project has overlapping hours for reviews and stand-ups. Everything else runs async with recorded walkthroughs, decision logs and written updates in your Slack or Teams.
How do we get started?
Book a 30-minute call or send a short brief. We come back within a few working days with a scope, a plan and a price. Work starts after an NDA and IP assignment are signed and your accounts are set up.
