Re-platform your product while customers keep using it

Re-platforming starts with an honest look at what you have. We review the codebase, the data model, the infrastructure, the deployment process and the dependencies that are out of support. We interview the people who run the product, because the real constraints are often in their heads, not in the repository.

The audit ends with a recommendation for each part of the system: keep, refactor, rewrite or retire. A full rewrite is tempting and usually the most expensive and risky option, because the old system holds years of small business rules that nobody wrote down. Where we can, we prefer the strangler pattern: build new components beside the old ones, route traffic across gradually, and retire legacy parts only when the replacement is proven.

You get a written report with findings ranked by risk and cost, a target architecture, and a migration plan with ranges for time and effort. The audit typically takes two to three weeks and is a useful document even if you decide to do the work elsewhere.

Moving live data is the highest-risk part of any migration. We rehearse it. Scripts run against copies of production data, reconciliation reports compare record counts and totals between old and new, and we repeat until the numbers match. Only then do we schedule the real move, usually in a low-traffic window with a rollback plan that has itself been tested.

Customers move in waves. A friendly internal or pilot tenant goes first, then a small group, then the rest, with monitoring watching error rates and performance at each step. If something is wrong, the wave rolls back and the customer sees nothing.

Saudi requirements shape the target platform. Personal data is covered by the Personal Data Protection Law, so we check where data sits and how deletion and export work. If you issue invoices, ZATCA e-invoicing integration is checked during the migration. If your customers are regulated or in government, hosting in the Kingdom and alignment with National Cybersecurity Authority controls and Communications, Space and Technology Commission cloud rules may drive the platform choice, and migration is a good moment to make that change once.

The point of re-platforming is not new technology. It is a team that can ship a change on a Tuesday afternoon without fear. That needs an automated test suite on the revenue paths, a deployment pipeline that anyone on the team can run, and environments that match each other.

We also reduce the knowledge risk. Architecture notes, runbooks, an onboarding guide for new developers, and a decision log explaining why things are built the way they are all come with the handover. Where useful, we pair with your developers during the migration so the skills stay in the building.

A typical staged migration takes three to six months for a product of moderate size, with the first customers on the new platform within the first two months. We can keep supporting the platform afterwards, or hand it over fully. The code, the infrastructure definitions and the documentation are yours either way.
