Legacy Migration
Expertise
• Systems running on outdated or unsupported platforms
• Applications built with deprecated technologies (COBOL, VB6, FoxPro)
• Software with high maintenance costs and difficulty finding skilled developers
• Systems that cannot integrate with modern tools and APIs
• Applications with security vulnerabilities due to lack of updates
• Monolithic architectures limiting scalability and agility
• Systems causing compliance or regulatory challenges
• Rehosting (Lift & Shift): Quick migration to cloud with minimal changes
• Replatforming: Minor optimizations while moving to new platform
• Refactoring: Restructuring code for cloud-native benefits
• Rearchitecting: Rebuilding with modern architecture patterns
• Rebuilding: Complete rewrite using modern technologies
• Replacing: Switching to SaaS or COTS solutions
We assess your specific needs to recommend the optimal approach.
• Small Applications (< 100k LOC): 3-6 months
• Medium Applications (100k-500k LOC): 6-12 months
• Large Enterprise Systems (> 500k LOC): 12-24 months
• Complex Ecosystems: 18-36 months with phased approach
Factors affecting timeline include data volume, integrations, business logic complexity, compliance requirements, and testing needs. We provide detailed timelines after initial assessment.
• Comprehensive data profiling and quality assessment
