Legacy System Modernization for the Software Your Business Runs On

Legacy system modernization moves the software your business depends on from outdated technology to supported technology, while keeping the data and workflows that still work. Depending on the system, that means upgrading the code, replacing it one part at a time, moving it to the cloud or rebuilding it. Application modernization is the same work, focused on one app.

Usually step by step. Replacing one part at a time keeps the business running, shows progress early and keeps each change small enough to test. A full rewrite makes sense when the old code can't be saved or the technology has no upgrade path. After the review we recommend one and explain why.

Until a new part is ready, the old system stays in use. Your team tries the new version on a staging copy first, and we schedule each switch-over with you at a time that suits your work.

We run trial migrations on a copy of your data first. Along the way we remove duplicates, fix broken records and agree with you on what to archive. Then we compare record counts and totals between the old and new systems, and the final move happens once you approve the results.

We read the code and the database, and we talk with the people who use the system every day. Our senior engineers use AI coding tools to read and summarize old code faster, and an engineer reviews every finding. The result is a written map of the screens, rules and data that stays with you.

Common examples are .NET Framework apps, Visual Basic 6 and other desktop apps, Classic ASP, Microsoft Access databases, AngularJS and older PHP sites, often on an aging Windows server. We move .NET Framework to modern .NET, desktop apps to the web and data to SQL Server or PostgreSQL. That is not the full list, so ask about yours.

Not always. Moving to Microsoft Azure or AWS makes sense when the old server is a risk or nobody wants to manage hardware anymore. We recommend it after the review. For website hosting, business email and Microsoft 365, see our IT support services.

It depends on the size of the system, the state of its code and data and the path you choose. After a short call we send a proposal with the approach, phases, timeline and cost. Because the work runs in phases, the first modernized part can go live before the rest is finished.

Your team, ours or both. The code lives in your repository and any cloud account is in your name, so any capable team can take it over. We also offer maintenance billed monthly, with no minimum term. To add engineers to your own team instead, see our IT staff augmentation services.
