Request a QuoteLegacy systems are the silent anchor holding many businesses back. Outdated technology increases maintenance costs, limits your ability to innovate, creates security vulnerabilities, and makes it increasingly difficult to hire developers willing to work with aging codebases. At CodeMetrics, we specialize in breathing new life into legacy applications by migrating them to modern, maintainable, and scalable platforms.
Our migration approach is methodical and risk-averse. We begin with a comprehensive assessment of your current systems, documenting every dependency, data flow, integration point, and business rule. This deep understanding allows us to design a migration strategy that preserves all critical functionality while introducing modern architecture patterns, improved performance, and enhanced security.
We support multiple migration strategies based on your business constraints: lift-and-shift for quick cloud migration, strangler fig pattern for gradual replacement, and complete rewrites when the legacy system is beyond incremental improvement. Throughout the process, we maintain parallel operations and implement comprehensive testing to ensure zero data loss and minimal disruption to your daily operations.
Key Benefits
Zero Data Loss Guarantee
Our rigorous data migration process includes automated validation, checksums, and parallel-run verification to ensure every record is transferred accurately and completely.
Minimal Business Disruption
Phased migration with rollback capabilities at every stage ensures your team can continue working throughout the transition with minimal downtime.
Reduced Maintenance Costs
Modern architectures are easier and cheaper to maintain, with better tooling, larger talent pools, and fewer unexpected failures compared to aging legacy systems.
Improved Security & Compliance
Modern platforms receive regular security updates and support current compliance standards, eliminating the vulnerabilities inherent in unsupported legacy technologies.
Our Methodology
Legacy System Assessment
We conduct a thorough audit of your existing system, documenting architecture, dependencies, data models, integration points, and business rules to create a complete migration blueprint.
Target Architecture Design
We design the modern target architecture, selecting appropriate technologies, cloud services, and deployment strategies that meet your performance, scalability, and budget requirements.
Phased Migration Execution
We migrate functionality and data in carefully planned phases, running the old and new systems in parallel with automated validation to catch discrepancies before cutover.
Validation, Training & Decommission
After thorough validation and user acceptance testing, we train your team on the new system, provide documentation, and assist with decommissioning the legacy platform.
Frequently Asked Questions
We use automated ETL pipelines with row-count validation, checksum verification, and sample-based manual review at every stage. We run parallel systems during the transition period so any discrepancies can be caught and corrected before the legacy system is decommissioned.
Yes, we have experience migrating systems built on COBOL, Classic ASP, Visual Basic 6, legacy PHP, and other aging technologies. We reverse-engineer business logic, document undocumented features, and rebuild them using modern frameworks.
Small to medium migrations typically take 3 to 6 months, while large enterprise migrations can take 6 to 18 months depending on complexity. We deliver in phases so you start seeing benefits early, and we always provide detailed timelines during the assessment phase.
