The villain

The Legacy Trap

It still works — until the day it doesn't.

Security warnings

Unsupported versions with known vulnerabilities.

Fear of deploying

Every release might break something old.

Talent drain

Good engineers don't want to work on it.

Slow everything

Pages, builds and new features all crawl.

Failed reviews

Big clients reject you at the security review.

The cost of waiting

Every month on old versions adds security risk, slower releases and engineers who don't want to touch it.

It's not your fault. The tools that got you here won't get you there.

Every great product hits this wall. Here's who gets you over it.

FAQ

Questions, answered.

Straight answers about risk, timing and cost.

Will the app keep running during the upgrade?

Yes. We upgrade in small steps, each one tested and released, so users never see a big-bang switch.

What if there are no tests?

We add tests around the critical flows first, so every upgrade step can be checked automatically.

Upgrade or rebuild?

We decide after the audit: step-by-step upgrades when the core is sound, a new custom version when the old one holds the product back. Either way you get a fixed price and date.

How much does the move cost?

The price is fixed for the agreed scope and set after a short audit, before work starts. No hourly billing.

How long does it take?

Most moves take weeks, not months. You get a fixed timeline after the audit, and a working prototype of the new version in 1 day.

What if something goes wrong?

The old system stays live as a rollback until the new one is verified side by side, so you can always switch back.

Who owns the result?

You do, 100% — the code, the repository, the data and every account.
