Your VB6 app still runs the business. It also still terrifies you.
It was built 20 years ago by a programmer who is long gone. Nobody left on staff understands the code. It only runs on one specific old desktop that everyone’s afraid to restart. And every year, the risk of it finally dying — taking your operations down with it — gets a little higher.
Here’s the good news: you don’t have to keep living with it, and you don’t have to start from scratch either.
At Keene Systems, we specialize in exactly this scenario. We take legacy VB6, Classic ASP, Access, and FoxPro systems and convert them into modern ASP.NET Core web applications — preserving the business logic and workflows your company has refined over decades, while finally giving you something your team can access from any browser, any location, any device. Along the way, we also look for the obvious improvements: the reports that take all weekend, the manual steps nobody’s questioned in years, the workarounds that grew up around the old system’s limitations.
This isn’t a rip-and-replace gamble. It’s a careful modernization process built by a team that’s been doing this since before ASP.NET existed — we’ve been building custom software since 1987.
If your business is still being held hostage by code nobody can touch, let’s talk about what modernizing it actually looks like.
