What Our Clients Say About Us

Frequently Asked Questions

Migrate when annual maintenance exceeds 60-70% of your IT budget, when the original vendor has ended support, when you cannot hire developers for the legacy stack (COBOL, VB6, classic ASP), when security vulnerabilities cannot be patched, or when the system blocks integration with modern tools. If three or more of these apply, migration should be a priority within 12 months.

Strangler fig migration incrementally replaces legacy components one module at a time while both systems run in parallel, reducing risk but extending the timeline to 6-18 months. Big bang migration replaces the entire system at once over a cutover weekend, which is faster but carries higher risk of downtime and data issues. We recommend strangler fig for mission-critical systems and big bang only for smaller, well-understood applications with comprehensive test coverage.

We use five key risk controls: parallel running (old and new systems side-by-side for 2-4 weeks), automated data validation with row-count and checksum verification, feature-flag-based rollback capability, comprehensive regression testing (typically 200-500 test cases), and phased user rollout starting with a pilot group of 10-20% of users before full cutover.

Cost depends on system complexity, data volume, and integration points. A small application migration (single database, fewer than 50 screens) typically costs $50,000-$150,000. Mid-size ERP or CRM migrations run $200,000-$800,000. Enterprise-scale migrations with multiple interconnected systems range from $500,000 to $2M+. We provide detailed estimates after a 2-3 week discovery phase that maps all dependencies, data volumes, and business rules.

We follow a five-step process: data profiling to understand schemas and quality issues, cleansing rules to fix inconsistencies, ETL pipeline development (using tools like Azure Data Factory or Apache NiFi), iterative test migrations with automated validation reports, and final cutover with rollback scripts ready. For large databases (100GB+), we use change data capture (CDC) to sync delta changes during the parallel running period.
