Legacy System Rescue & Migration

We help companies rescue systems that block growth, crash during updates, or no one wants to touch anymore. First we map data, integrations, SEO, and critical processes. Then we design a controlled rewrite or phased migration to a modern Node.js / Next.js stack.

Without controlled modernization

Your software is holding back every change the company needs

Developers say it can't be done, it will be expensive, or they'd rather not touch it. Fear of old code then stalls sales, marketing, and customer support. A system that was supposed to accelerate the company becomes a bottleneck.

Risk

Outdated systems often run on libraries and versions that are no longer fully supported.

Slow development

Even a small modification takes a long time because no one knows what will break after the change.

Outages

Hidden bugs in old databases and integrations cause random operational problems.

Solving the problem

Node.js integration bridges

We create a thin API layer that connects your old system (Pohoda, SAP, custom PHP) to a modern frontend without needing a complete overhaul.

Automated data flows

We configure XML feeds, CSV imports, and database synchronizations so data doesn't move between systems via manual entry.

TypeScript in critical areas

We write integration points so the system catches data format changes from partners before the customer sees a problem.

A second life for old systems

Controlled modernization without chaos, data loss, and unnecessary risk.

A Way Out of Technical Debt

A system built years ago by one developer can become a business risk when that person is gone and nobody wants to touch the code. Every new feature takes too long and threatens to break something else. That is technical debt. We help untangle it and move the system into a modern Node.js / Next.js ecosystem while protecting what still generates revenue today: data, orders, SEO, integrations, and daily operations.

What we can rescue

01
E-commerce monolithsSlow Magento 1, old PrestaShop, or an overloaded WooCommerce.
02
Outdated B2B portalsCustom systems in old PHP that do not meet today's security standards.
03
Broken integrationsData bridges that lose orders between the web and the ERP system.
04
Critical dataBefore rewriting, we prepare backups, control exports, and data comparisons both before and after migration.
Process

How system rescue works

01

Audit and
mapping

Old code, database structure, integrations, and critical processes are mapped first.

02

Backups
and data checks

Exports, backups, and comparison checks make it clear what is being migrated.

03

Parallel
development

The new architecture is built alongside the existing system so operations do not have to stop.

04

Controlled
go-live

The transition happens only after testing, data validation, and rollback planning.

Audit first, rewrite later

We don't dress up an old backend in a new design and pretend migration is just a technical formality. With legacy systems, preparation is everything: data mapping, backups, testing, integration checks, and a rollback plan. Only then does it make sense to rewrite the system core or gradually replace it with a new architecture.

01
High cautionBacking up and testing every table before the actual go-live.
02
SEO protectionWe check redirects, sitemaps, and important URLs as part of the migration.
03
Code handoverYou receive a clean repository, documentation, and a system that a modern developer can easily take over.
04
Rollback planBefore launch, we know how to safely revert if production reveals an unexpected issue.

The goal is to minimize downtime or avoid it entirely. We prepare the new system in parallel, test data and critical scenarios, and schedule the hard launch only when the procedure and rollback plan are completely clear.

SEO is treated as its own part of the migration. We prepare a URL map, 301 redirects, a metadata audit, a sitemap, and post-launch monitoring. The goal is for Google to understand the transition without unnecessary organic traffic loss.

This is common with legacy systems. First, we figure out how the database, business logic, and integrations work. Only then do we propose what to rewrite, what to replace, and what to temporarily maintain via an integration layer.

We do not migrate blindly. First comes an inventory of critical features, backups, a test migration, and control scenarios. Go-live happens only when the success path and rollback path are clear.
