A Magento or Adobe Commerce migration without stopping revenue takes 3 to 6 months with the Strangler pattern: each function migrates in waves validated in production before the next, keeping checkout and catalog live throughout the process.
Big-bang migrations require maintenance windows, catalog freezes, and high rollback risk. For e-commerce operations with meaningful revenue, this model is unacceptable to the board.
The Strangler Fig pattern solves this: new capabilities are built alongside the legacy system, traffic migrates gradually, and the monolith shrinks until it can be decommissioned — with no commercial interruption.
Phase 2 of the Magecore method (Performance Engineering) applies the Strangler Pattern with AI-powered predictive monitoring throughout the transition.
Mid-size operations typically take 3 to 6 months. Timeline depends on catalog size, integration volume, and accumulated technical debt.
Documented Magecore cases include M1→Adobe Commerce Cloud migration with -41% TCO and +22% conversion over 12 months, using exactly this progressive approach.

Between 3 and 6 months, using the Strangler pattern and progressive migration, without stopping revenue during the process.
Duration depends on catalog size, integrations, and accumulated technical debt. Each migration wave is validated in production before the next.
For migrations to modular architecture with observability, 25% to 50% reduction in infrastructure TCO over 12 months is a realistic target for mid-size operations.
The exact percentage depends on the starting point: operations with high reactive legacy costs tend toward the upper range; each case is quantified in the diagnostic.
