Legacy Integration

We connect new software with your existing systems. No data is lost, no processes are interrupted.

We know the situation: you have a management system that's been running for 15 years, an ERP nobody dares touch, and an Access database holding half the office together. We'll never tell you to throw everything away and start over. It's unrealistic and expensive. What we do is build bridges: we connect new systems to old ones so they talk to each other. Synchronized data, automated processes, zero duplicate entries. Your team keeps using what they know while new tools feed from the same data.

Legacy Integration - i3k
01

System Mapping

Before writing a single line of code, we understand what you have. Databases, APIs, shared files, Excel sheets acting as master — everything. We draw a complete map of data flows and identify integration points.

02

APIs & Middleware

We create intermediate layers that translate data between old and new systems. REST APIs, message queues, ETL pipelines — we choose the right tool based on what's needed. The result: systems talk to each other without anyone changing how they work.

03

Gradual Migration

We don't pull the plug on the old system overnight. We run old and new in parallel, migrate data progressively, and only when everything is verified do we decommission the legacy. Zero surprises.

04

Complete Documentation

Every integration is documented in detail: data flows, formats, field mappings, recovery procedures. If the vendor or IT team changes down the road, anyone can understand how the system works.

How We Work

1

Technical Audit

We analyze all systems involved: software versions, data formats, communication protocols. We identify risks and critical points.

2

Integration Design

We design the integration architecture: which systems talk to which, in what direction data flows, how often, and what happens when something goes wrong.

3

Development & Testing

We build integrations one at a time, testing with real data in a staging environment. Each connection is verified before going to production.

4

Assisted Go-Live

We activate integrations in production with our team present. We monitor data flow for the first weeks and intervene in real time if needed.

What You Get

No data lost in transition — migration verified record by record

Your team doesn't have to change how they work overnight

Elimination of duplicate entries across different systems

Data always synchronized between old and new in real time

Complete documentation for future autonomous maintenance

Gradual approach that reduces risk at every step

Legacy systems aren't a problem — they're a resource containing years of data and processes. We integrate them with the new without losing anything, at your pace.
