Custom legacy application migration services
Our migration specialists have modernized systems ranging from 20-year-old mainframes to early cloud deployments. They understand both legacy technologies and modern architectures, ensuring smooth tra...
We evaluate technical debt, dependencies, data models, and business logic to design a phased migration plan that minimizes disruption and maximizes value.
We implement the strangler fig pattern to gradually extract functionality into new microservices, redirecting traffic as each component is ready.
We design ETL pipelines with data validation, reconciliation checks, and rollback mechanisms to ensure zero data loss during migration.
We create anti-corruption layers and API facades that allow new systems to interact with legacy data and logic without tight coupling.
We refactor applications to leverage cloud elasticity, managed databases, serverless functions, and auto-scaling for improved performance and cost efficiency.
We create comprehensive documentation, architecture decision records, and runbooks so your team can confidently maintain and extend the new system.
"They migrated our 15-year-old mainframe system to the cloud without a single minute of downtime. Our team didn't even notice the switch."

Frequently Asked Questions
Have more questions? Talk to an expert — we're happy to help.
Timelines vary by system complexity. Small systems can be migrated in 3-6 months, while enterprise systems may take 12-24 months with phased delivery. We show value from the first sprint.
We use the strangler fig pattern for incremental migration, maintain parallel systems during transition, implement comprehensive testing, and have rollback plans for every phase.
Yes. We use techniques like database replication, feature flags, and traffic switching to migrate with zero downtime. Users never experience disruption.
Data integrity is our top priority. We implement validation checksums, reconciliation reports, and parallel running to verify every record is correctly migrated before decommissioning legacy systems.
