compare cutover approaches and choose one with justification.
Planned topics
- Big bang: everything switches at once; fast, but highest risk and hardest rollback.
- Phased by capability: move catalog, then checkout, then returns; needs coexistence.
- Phased by store or region: pilot stores first, then waves; limits blast radius.
- Parallel run: both systems run and results are compared; safe but costly and needs reconciliation.
- Choose by business risk tolerance, data coupling, peak calendar, and team capacity.
