Legacy app modernisation that rebuilds PHP, .NET, VB or jQuery systems on Next.js and PostgreSQL with full data migration. Modernisation services from $1,500 to $2,500 in 16 to 28 days.
The problem
Many businesses in the UAE and India run on software written ten or fifteen years ago: a PHP 5 portal, a VB6 desktop tool, a Classic ASP intranet, a jQuery app nobody can change. It works until it does not: the developer is gone, the server cannot be patched, it fails on mobile, and each new feature takes months. Replacing it wholesale looks like a six-figure project, so it limps on and the risk grows.
What we build
We modernise in stages you can afford: first we read the old code and database and produce a feature and data inventory, then rebuild the highest-value modules on Next.js, Node.js and PostgreSQL, migrate the data with reconciliation, and run old and new side by side until cut-over. Claude digests the legacy codebase and documents every rule and report, Claude Code and Cursor regenerate them as tested modules, DeepSeek helps translate bulk legacy SQL and stored procedures cheaply, and we review security and data integrity by hand. Full source code, modern hosting and a fixed price that never exceeds $2,500 per phase.

FAQ
Legacy App Modernisation: common questions
How much does legacy modernisation cost?
Between $1,500 and $2,500 per phase, delivered in 16 to 28 days. Large systems are split into phases by module so each one stays within the $2,500 ceiling and delivers value on its own.
Will our staff have to relearn everything?
No. We keep the workflows and terminology your team knows while fixing the pain points, and run old and new in parallel so people switch at their own pace.
What if we do not have the original source code?
We can still rebuild from the database, screens and your team's knowledge. The inventory phase documents behaviour by observation, and the new app is verified against real historical data.
