Modernizing Legacy Systems

Usually, no. Full replacement is expensive, risky, and often unnecessary. We typically modernize incrementally: wrap legacy systems with APIs, migrate low-risk components first, preserve critical business logic, and only replace what truly needs replacing. Most clients save 60-70% compared to full replacement approaches while reducing risk dramatically.

We use a multi-layered approach: parallel running of old and new systems during transition, automated data validation at every step, real-time sync mechanisms, comprehensive backup procedures, rollback capabilities at each phase, and extensive testing before each cutover. We've migrated over 100 enterprise systems without data loss.

We design for zero downtime. Our approach: migrate during off-peak hours, use blue-green deployment strategies, implement gradual rollouts by department/location, maintain fallback to legacy systems if needed, and provide 24/7 monitoring during transitions. Healthcare and financial services clients regularly migrate mission-critical systems with zero downtime.

It varies, but typical timelines: assessment and planning (4-6 weeks), pilot phase with one system/department (8-12 weeks), incremental rollout (3-9 months depending on scope). Unlike 'big bang' replacements that take years, our incremental approach delivers value within the first 90 days and continues progressively.

Yes, in most cases. We specialize in working with legacy databases—Oracle, DB2, SQL Server, even hierarchical databases. We create integration layers that allow modern applications to work with existing data stores. You can migrate databases gradually or not at all, depending on your needs and constraints.

Compliance is built into our process. We: conduct compliance assessments upfront, maintain audit trails throughout migration, ensure data residency requirements are met, implement required security controls, provide compliance documentation, and work with your legal/compliance teams. We have extensive experience with HIPAA, SOX, GDPR, and industry-specific regulations.
