Title: Replace legacy software without a big bang | AI Heroes URL: https://aiheroes.io/en/legacy-software Description: An old custom system or a platform that no longer keeps up, rebuilt alongside the old one and moved over in phases. A six-day start sprint with a migration plan, from €8,000. # Your system dates from 2011 and nobody dares to touch it AI Heroes rebuilds your legacy system with today's know-how, alongside the old one, and switches the old one off only when the new one runs. The same goes for a platform that no longer keeps up. The first step is a six-day start sprint, from €8,000. Plan a start sprint How to start ## What we do - Work out what the old system does · From the code and the data, including the things nobody remembers. - Build the new system · With the connections the old one never had, and room to grow. - Move data over in parts · Every step checked, so nothing gets lost. - No big bang · The old system keeps running until the new one demonstrably works. ## Switching over without everything grinding to a halt The risk of replacing is in the switch. So we always do these three things. - First · Connections first · We first connect the new system to what stays: your ERP, CRM, accounting or web shop. - Then · Data in parts, with checks · We move your data over in parts and check every step, so nothing gets lost. - Only when it runs · The old one stays on · The old system keeps running until the new one demonstrably works. Only then do you switch it off. ## How to start: the start sprint In the start sprint we work out what the old system does and what it is tied to. From that follow the architecture of the new system and a phased migration plan. - 6 days: from kick-off to result - €8,000: from, a fixed price per start sprint - 2 weeks: from the first call to the start After six days you have An inventory of the old system, the architecture of the new one, a phased migration plan and the business case. [How the start sprint works](https://aiheroes.io/en/start-sprint) A build has a fixed price per project, from €15,000. What you paid for the start sprint is deducted from it. ## Included in every build - Business case first · Before we build, you know what it costs, what it returns and when it pays for itself. - Compliance by design · AI Act classification, logging, human oversight and European hosting are part of the design. - Your people can work with it · We train the team that will use the system on the system itself. That also covers Article 4 of the AI Act. - Not tied to one AI vendor · You can switch AI models without rebuilding. Everything comes with documentation. What matters most here: everything is documented. Never again a system nobody understands. [How we work](https://aiheroes.io/en/how-we-work) ## Frequently asked questions ### What if nobody knows what the old system does any more? We work that out in the start sprint, from the code and the data. After that, what the system does is written down. ### Does everything have to move over at once? No. We switch in phases, and the old system keeps running until the new one works. ### What if the old supplier does not cooperate? Then we work with what there is: the data, the exports and the system itself. In the start sprint you see what that means for the schedule. ### How long does it take? The start sprint takes six days. The build then usually takes two to twelve weeks in total; the switch happens in phases. ### What does it cost? The start sprint costs from €8,000. A build has a fixed price per project, from €15,000; the amount for your system is in the business case. Who leads this at AI Heroes David Homan Co-Founder, software and compliance David leads the build, from prototype to a system that runs in your own landscape. AI Act classification, logging, security and hosting are built into the design from the start.
