If your business has been running the same web application for the past decade or more, there's a reasonable chance it's built on Classic ASP Microsoft's original server-side scripting platform, introduced with IIS 3.0 back in 1996. In 2026, Classic ASP is officially unsupported by Microsoft, yet thousands of Australian businesses still depend on it every day. So what should you do?
The Case for Maintaining Classic ASP
The most compelling argument for keeping your Classic ASP application running is simple: it works. If your application is stable, your team knows how to use it, and the business processes it supports haven't fundamentally changed, then forcing a migration purely because the technology is old can introduce significant risk without delivering proportionate benefit.
Classic ASP still runs perfectly well on modern Windows Server and IIS. Microsoft's IIS 10 (included with Windows Server 2022) fully supports Classic ASP execution it's simply no longer receiving new feature development.
The Case for Modernising
That said, there are clear signals that modernisation should be seriously considered. If your application handles sensitive data, it almost certainly has security vulnerabilities that simply cannot be patched without a rewrite Classic ASP predates many of the security primitives we now take for granted.
Modern frameworks also offer dramatically better developer tooling, automated testing, containerisation and CI/CD pipelines. If your team is struggling to find developers willing to maintain VBScript, the talent pool problem alone may force your hand.
A Pragmatic Middle Ground
At Electriclatte, we help clients assess their Classic ASP applications honestly. Some are genuinely low-risk and cost-effective to maintain. Others are quietly accumulating technical debt and security exposure that will eventually demand action. The answer is rarely black-and-white it's a risk-adjusted business decision that deserves proper analysis before committing budget in either direction.
