Engineering case study
Reduced migration risk while modernizing a production engineering system
Celebratix · Dec 2025 - Present
A production dashboard needed a framework migration while product continuity and rollback safety remained critical.
Problem
The migration was technically broad and operationally risky because it involved a 460-file cutover across a live product surface.
Constraints
- Production continuity had to be protected
- Rollback needed to be fast and documented
- The migration touched a large product surface
My Role
Planned the migration strategy, coordinated implementation, reviewed architectural decisions, and owned the production rollout.
Decision
Use a 26-step migration plan and dual-runtime Docker image to make the rollout reversible.
Trade-offs
- More upfront planning in exchange for lower production risk
- Temporary runtime complexity in exchange for a safe rollback path
Execution
- Defined the migration plan and rollout sequence
- Coordinated the 460-file cutover
- Documented rollback and owned production deployment
Outcome
The framework swap became a 2-minute reversible deploy instead of a one-way production migration.
Lessons Learned
- Architecture work should include operational rollback design
- Reversibility makes high-risk technical change easier for the business to accept
Technology Context
- Next.js
- Vite
- React Router
- Docker
