Migrations · off the legacy stack
Move off the legacy stack without losing sleep
Incremental, reversible, boring on purpose. We map your data, traffic, and edge cases first, then move in slices you can roll back, while the old system keeps running.
What this engagement actually looks like, start to ship.
A migration engagement starts with a data and traffic audit before anyone quotes a build: the edge cases are what make a migration hard, so we find them first. Then we move in reversible slices, strangler-fig style, with the old system serving traffic until the new one has earned it.
Every engagement ships a redirect map that preserves your SEO, parity checks against the old system, and a cutover runbook with a rollback plan. Downtime, if any, is a planned few minutes, not a gamble.
Scoped, priced, and shipped before.
- Vibe coding cleanupVibe coding cleanup for apps that worked in the demo and broke in the wildYou built it with AI, it looked finished, and then real users arrived. We take the code you already have, find what is actually wrong with it, and make it something you can keep running. You keep the product. We replace the parts that cannot hold.See the build
- Platform exitMove your AI-built app off the platform and onto code you actually ownLovable, Bolt, Replit, v0, Bubble: they got you a real product faster than hiring could have. Then the thing you built started mattering, and the platform turned out to be holding the repo, the database, the deploy button, and the invoice. We move it out. Same product, your infrastructure, no downtime.See the build

Boring tools, on purpose.
We pick tools for how they behave in year three, not for the launch-week demo. Here is what we reach for in this work, and the one-line reason each earns its place.
- Next.jsWhere most of our migrations land: server-first, and fast to build against.
- PostgreSQLThe relational target we reconcile most legacy schemas onto.
- PayloadWhen the old CMS needs replacing, not just the framework around it.
- TypeScriptTypes catch the schema mismatches a migration is full of.
- VercelPreview the new system on real data before a single user moves.
- SentryParity issues surface as errors, not as silent data drift.
Most migrations fail on a promise
Most migrations fail because someone promised a clean cutover in a weekend. We do not. We map your data, your traffic, and your edge cases first, then move in slices you can roll back, so the old system keeps running until the new one has earned the traffic.
The work is unglamorous on purpose: schema reconciliation, redirect maps, dual-writes, and a lot of verification. That is exactly why it goes smoothly.
What we move teams off
We have moved teams off Rails, WordPress, Firebase, and homegrown PHP onto Next.js with Postgres or Payload. If you are on something older or stranger, the playbook is the same: map, dual-write, verify, cut over.
Search rankings are part of the deliverable, not an afterthought: a complete redirect map and preserved URL structure where it matters, so the traffic you have built up moves with you.
How we scope and price
Migrations are priced off your data and your edge cases: the things that actually make one hard, not a headline number. We map them first, then quote in slices you can stop and restart.
- A data + traffic audit before anyone quotes a build
- Reversible slices: the old system keeps running until the new one earns the traffic
- A redirect map and parity checks in every engagement
- A cutover runbook and rollback plan, not a gamble
Send us your current stack and we’ll scope the move (shape, timeline, and cost) on a quick call.
Common questions.
01Will the site go down during the migration?
No. We run old and new side by side and shift traffic gradually. If something looks wrong, we route back. Downtime, if any, is a planned few minutes, not a gamble.
02What about our search rankings?
We build a complete redirect map and preserve URL structure where it matters. SEO continuity is part of the deliverable, not an afterthought.
03How long does a migration take?
It scales with your data and edge cases, not the calendar. We move in reversible slices: old and new run side by side, so there is no big-bang cutover date to miss. A focused migration is weeks; a large legacy system with years of data is a phased engagement.
04What can you migrate off?
We have moved teams off Rails, WordPress, Firebase, and homegrown PHP onto Next.js with Postgres or Payload. If you are on something older or stranger, tell us: the playbook (map, dual-write, verify, cut over) is the same.
