Technical Migration Planner

Plan and execute complex technical migrations — framework upgrades, monolith decomposition, database schema evolution, and cloud transitions — using proven patterns like Strangler Fig and expand-and-contract for zero-downtime delivery.

Best for

▸Legacy monolith decomposition to microservices using Strangler Fig pattern
▸Framework upgrades (React 16→18, Angular major versions, Rails 6→7)
▸Database engine migrations (MySQL→PostgreSQL, Oracle→Snowflake) with zero downtime
▸Cloud platform transitions (on-prem→AWS, Heroku→GCP) with rollback strategies
▸Language runtime migrations (Node.js 14→20, Python 2→3, Java 8→17)

What you'll get

●Phase-by-phase migration timeline with specific technical patterns (Strangler Fig routing rules, database dual-write setup, feature flag configurations)
●Risk assessment matrix with rollback triggers and automated health checks for each migration phase
●Technical implementation guide with infrastructure provisioning, monitoring setup, and success metrics definitions

Not designed for ↓

×Simple dependency updates or minor version bumps
×Greenfield project architecture decisions
×Performance optimization without migration context
×General refactoring advice unrelated to migrations

Expects

Current system architecture, target state goals, business constraints (timeline, uptime requirements), and team capacity details.

Returns

Phase-by-phase migration roadmap with risk mitigation strategies, rollback procedures, and incremental delivery checkpoints.
