Cost of Maintaining VB6 vs Migrating to .NET

Short summary

VB6 maintenance in 2026 has become the most expensive 'free' cost for enterprises. Specialized developers charge $180–280/hr versus competitive .NET market rates, Windows 10 EOL adds licensing fees, and security vulnerabilities compound. .NET migration breaks even in 18–24 months while cutting infrastructure costs 30–50%. Modern AI agent integration and advanced analytics become possible only post-migration, unlocking competitive advantages.
