Legacy Modernization & Migration

Legacy Modernization & Migration

Legacy system modernization for US companies — PHP to React, monolith to microservices, cloud migration, and zero-downtime cutovers.

How We Work

Legacy Modernization Timeline

GKAI Studio scopes legacy modernization projects in four phases: discovery (1–2 weeks), design and architecture (1–2 weeks), build with weekly demos (4–12 weeks), and production launch with documentation. Typical US engagements ship in 6–16 weeks depending on scope and integrations.

• Week 1–2: Requirements workshop, technical audit, success metrics
• Week 3–4: UX flows, API contracts, sprint roadmap
• Week 5+: Agile build, staging demos, integration testing
• Launch: AWS deployment, monitoring, handoff and optional retainer

Legacy Modernization Trends in 2026

US businesses investing in legacy modernization in 2026 prioritize production reliability over demos — eval datasets, observability, and human-in-the-loop guardrails are standard. AI-assisted development accelerates delivery but senior architecture and integration work still determines whether projects succeed in production.

Legacy Modernization for US Startups

Startups need focused MVPs — one core workflow, one integration surface, and measurable ROI within 90 days. GKAI Studio recommends fixed-scope engagements with clear phase-2 options instead of open-ended hourly contracts that drift scope.

Legacy Modernization for US Enterprises

Enterprise deployments require SSO, audit logs, role-based access, data residency decisions, and phased rollouts by department. We integrate with existing CRMs, ticketing systems, and identity providers — augmenting workflows instead of asking employees to adopt a separate tool.
