API Migration

Migrating legacy APIs to modern architectures is one of the most risk-laden phases of any cloud-native transformation. APIs are deeply embedded in consumer workflows — breaking them breaks trust. Huco's API Migration practice applies a structured, phased approach that maps every upstream dependency, manages versioning carefully, and validates parity at every endpoint before cutover. We leverage declarative configuration and GitOps principles so migrations are reproducible, reversible, and auditable — enabling teams to move to modern, scalable API designs without disrupting the integrations that keep the business running.

• Comprehensive legacy API inventory, dependency mapping, and consumer impact analysis
• Phased migration pathways: REST, GraphQL, gRPC, and WebSocket modernisation
• Backward compatibility planning, versioning strategy, and deprecation governance
• Declarative, GitOps-compatible migration with full configuration version control
• Parallel run testing, traffic shadowing, staged rollout, and automated rollback capability
• Integration with modern API gateway platforms and service mesh architectures post-migration
