Application Modernization
Move off legacy systems without breaking what works
Legacy applications slow you down, cost more to maintain, and block new capabilities. We modernize incrementally — replacing what needs to change while preserving what works.
When This Fits
Your legacy application is too expensive to maintain
You can't add new features because the codebase won't support them
Your system can't scale or integrate with modern tools
You're stuck on an end-of-life framework or platform
What Clapself Owns
Application assessment and modernization roadmap
Architecture redesign (monolith to microservices, cloud-native)
Incremental migration with zero-downtime cutover
Data migration and validation
Testing, deployment, and production handoff
