What Is ASP Classic and VB6 Migration?

ASP Classic migration is the process of converting legacy Active Server Pages (ASP) web applications written in VBScript to modern frameworks like ASP.NET Core. VB6 migration involves modernizing Visual Basic 6 desktop applications to C#/.NET. These migrations are critical because:

  • 1. VBScript is deprecated — Microsoft is phasing VBScript out of Windows as a Feature on Demand before complete removal
  • 2. VB6 IDE unsupported since 2008 — While the runtime is still supported on Windows 11, the development environment ended mainstream support in 2005 and extended support in 2008
  • 3. Only 7% can find skills in-house — 74% of organizations must outsource legacy maintenance. VB6 ranked "most dreaded" language by developers
  • 4. Security vulnerabilities accumulate — OWASP and NCSC warn that legacy systems lack modern security controls and are prime targets for attackers

Key dates: VB6 IDE extended support ended (2008) | VBScript deprecated (Oct 2023) | VBScript becoming Feature on Demand (phased rollout)[1]

Key Challenges

Microsoft has deprecated VBScript and is phasing it out of Windows as a Feature on Demand before complete removal. Every ASP Classic page and VB6 component needs a clear path forward.

Industries Using Legacy VB6, ASP & Access Systems

Healthcare, finance, government, and manufacturing still run mission-critical operations on VB6, ASP Classic, and Microsoft Access. When these legacy systems fail, people notice.

Healthcare

73% of healthcare providers still use legacy systems. Patient data, scheduling, billing — HIPAA compliance gaps everywhere.

Financial Services

Banks, credit unions, insurance companies. VB6 handles payroll, transactions, and reporting. One outage costs millions.

Legacy System Migration FAQ

Common questions about ASP Classic migration, VB6 modernization, and VBScript deprecation

"Our systems have worked fine for 20 years. Why worry now?"

Because Microsoft is phasing out the technologies you depend on. VBScript was deprecated in October 2023 and is being removed from Windows as a Feature on Demand before complete removal. The VB6 IDE hasn't been supported since 2008. Classic ASP's future is tied to IIS support.

While the VB6 runtime is still officially supported on Windows 11, 69% of IT leaders say technical debt is limiting their ability to innovate. Only 7% of organizations can find VB6 skills in-house—the rest must outsource at premium rates.

"Can't we just keep patching and wait?"

Wait for what? VBScript is deprecated and Microsoft is actively phasing it out. Classic ASP's future depends on IIS support in future Windows Server versions. Organizations spend 70-80% of IT budgets on legacy maintenance—that's up to $30 million annually for large enterprises.

The cost of emergency recovery when your system fails is 10x the cost of planned modernization. Studies show companies that modernize see 14% reduction in IT costs and improved agility. Technical debt only accumulates—it doesn't fix itself.

"What if we don't have the source code anymore?"

You're not alone — 40% of VB systems have missing source code. Our specialists excel at reverse engineering legacy applications, documenting business logic, and creating maintainable replacements.

Even without source code, we can analyze the running application, extract database schemas, and rebuild critical functionality in modern platforms.

"How do you work with remote clients?"

100% of our work can be done remotely. Secure VPN access, screen sharing, remote desktop — we've supported clients across every timezone.

Most legacy Windows issues can be diagnosed and fixed without physical access. For complex migrations, we work in sprints with regular video calls and documentation.

"What does a risk assessment actually include?"

A complete inventory of all legacy components. Security vulnerability scanning. DCOM/COM+ configuration audit. IIS security review. Database health check. Backup verification.

You'll receive a detailed report with every risk scored by severity and business impact, plus a prioritized remediation roadmap. No surprises, no hidden problems.
