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. ### Why traditional migrations halt revenue 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. ### How Magecore executes zero-downtime migration Phase 2 of the Magecore method (Performance Engineering) applies the Strangler Pattern with AI-powered predictive monitoring throughout the transition. - Business domain mapping and prioritization by financial impact - Wave-based migration: checkout, catalog, integrations, and back office in controlled sequence - Production validation with conversion, latency, and error metrics before advancing - Observability (OpenTelemetry, dashboards) to detect regressions in real time - Complete documentation and modular post-migration architecture ### How long it takes in practice 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. --- ## /en/guide/adobe-commerce-precision-assessment # What is a Precision Assessment for Adobe Commerce / Magento? Magecore's Precision Assessment is an AI-assisted multidimensional diagnostic that identifies margin leaks and technical debt in Adobe Commerce / Magento operations, delivered in 1 to 3 weeks — not months — with a cost map in real currency and a clear recommendation: migrate, optimize, or maintain the platform. ### What sets it apart from a traditional audit Traditional consultancies deliver generic reports in 4 to 8 weeks. The Precision Assessment cross-references financial, technical, and operational data simultaneously, with AI analyzing codebase, infrastructure, logs, and costs. The result is not a vague list of recommendations. It is a leak map with financial projection and P&L-impact prioritization. ### Assessment deliverables At the end of 1 to 3 weeks, the client receives: - Margin leak map in real currency - Real vs perceived TCO - Architectural health score - Prioritized intervention list with projected ROI - Industry benchmark where applicable - Clear recommendation: migrate, optimize, or maintain ### What it costs The initial 30-minute conversation with Marcio Maciel and the pre-diagnostic with the three main areas of concern are free. The full Assessment is a fixed-scope project; investment varies by size and complexity and is presented after the initial conversation, with no sales pitch. --- ## /en/guide/reduce-ecommerce-tco # How to reduce TCO in Adobe Commerce / Magento operations? 25% to 50% infrastructure TCO reduction over 12 months is a realistic target for mid-size Adobe Commerce / Magento operations that migrate to modular architecture with observability, provided the starting point includes elevated reactive legacy costs. ### Where inflated TCO comes from In mature operations, TCO rarely sits in the platform license. The biggest leaks come from reactive maintenance, oversized infrastructure, fragile integrations, and obsolete extensions. A documented Magecore case mapped 38% of the IT budget to reactive Magento 1 maintenance and R$ 1.8M/year in invisible costs, before any migration. ### How Magecore reduces TCO Reduction comes from three combined levers, always measured against a baseline defined in the assessment: - Strangler migration to modular architecture: eliminates vendor dependency and reduces structural cost - Observability and predictive monitoring: cuts reactive incidents and firefighting hours - Integration and infra optimization: when the platform is not the bottleneck (8-day assessment avoided R$ 800K+ in unnecessary migration) ### Documented results Anonymized cases published on the site include -41% infrastructure TCO over 12 months (retail), R$ 2.1M in documented annual savings, and R$ 1.2M saved without platform migration when the assessment showed integrations were the bottleneck. Every recommendation is tied to P&L metrics: TCO, conversion, support tickets, LTV, or annual operational savings, with baseline before intervention and 12-month measurement. --- ## /en/guide/headless-magento-roi # Is it worth migrating monolithic Adobe Commerce to headless? Migrating monolithic Adobe Commerce to modular or headless architecture is worth it when the monolith limits margin, change velocity, or scalability and migration ROI exceeds the cost of maintaining the status quo — but in some cases the assessment shows integrations and infrastructure, not the platform, are the bottleneck. ### Signs that headless/modular makes sense Headless is not a trend. It is a response to concrete bottlenecks. The most common signals in Adobe Commerce / Magento operations: - Front-end team blocked by monolithic releases - Storefront performance limited by backend coupling - Inability to scale components independently during seasonal peaks - Dependency on a single vendor for any change - Reactive maintenance cost growing quarter over quarter ### When NOT to migrate Magecore has recommended clients not migrate when an assessment (8 days, AI-assisted) showed the platform was not the bottleneck: third-party integrations with cascading latency and undersized infrastructure during peaks were the culprits. In that case, the client saved R$ 800K+ in avoided migration cost and R$ 1.2M in the first year with surgical optimization. The decision must be based on P&L numbers, not tech trends or vendor pressure. ### How to calculate migration ROI The Precision Assessment projects current TCO vs post-migration TCO, conversion impact (checkout, performance), opportunity cost of slow releases, and incident risk. Every initiative in the 12-month Strategic Roadmap has explicit financial return attached — the same criterion used to measure ROI on technical interventions. --- ## /en/guide/adobe-commerce-vs-mage-os # Adobe Commerce vs Mage-OS: when is migration worth it? Migrating from Adobe Commerce to Mage-OS makes sense when licensing cost is material to the P&L, the operation does not depend on Adobe-exclusive features, and the team can sustain an open-source distribution — but in many cases the assessment shows optimizing the current installation or fixing integrations delivers more ROI than switching distributions. ### What changes in practice Adobe Commerce and Mage-OS share the same Magento Open Source core but diverge in licensing, update pipeline, and commercial support. The choice impacts TCO, patch velocity, and vendor dependency — not just the technical stack. Mage-OS eliminates Adobe license cost and offers a community distribution with predictable releases. Adobe Commerce maintains commercial SLA, enterprise features (advanced B2B, native staging, Adobe support), and Experience Cloud ecosystem integration. - Licensing: Adobe Commerce has annual cost by GMV/revenue; Mage-OS is open source - Updates: Adobe delivers patches via cloud; Mage-OS depends on community cycle + internal QA - Support: Adobe offers commercial SLA; Mage-OS requires internal team or specialized partner - Enterprise features: Adobe Commerce includes native B2B, advanced Page Builder, and integrated staging ### When to migrate to Mage-OS Migration to Mage-OS is financially attractive when Adobe license cost represents a relevant share of TCO and the operation does not use Adobe-exclusive features that justify the investment. - Adobe license above 15–20% of total platform TCO - B2C or simple B2B operation, no Experience Cloud dependency - Engineering team capable of sustaining patches and security - Assessment confirms the platform (not integrations or infra) is the cost bottleneck ### When NOT to migrate Magecore has recommended keeping Adobe Commerce when the assessment showed third-party integrations, mis-sized infrastructure, or custom extensions were the culprits — not the license. Migrating distributions without resolving underlying technical debt swaps a visible cost (license) for invisible risks (security, extension compatibility, downtime). The decision must be based on 12-month projected TCO, not just the licensing line item. - Operation depends on advanced B2B, native staging, or Experience Cloud integrations - Proprietary extensions with no Mage-OS community equivalent - Internal team without capacity to sustain patch and security cycles - Assessment indicates integrations or infra respond better to optimization ### How to decide with numbers The Precision Assessment projects Adobe TCO vs Mage-OS TCO over 12 months, including license, infra, maintenance, incident risk, and migration cost. Each scenario has explicit ROI tied to the P&L. The final recommendation (migrate, optimize, or maintain) is delivered with a cost map in real currency — not as generic technical opinion. --- ## /en/faq # Frequently asked questions ### Is Magecore a consultancy, agency, or boutique? Yes. Magecore operates as a consultancy and agency specialized in Adobe Commerce / Magento in Brazil. "Boutique" describes our delivery model — senior team, partners leading, fixed scope — not a different service category. We offer precision assessments, zero-downtime progressive migration, and strategic roadmaps for e-commerce operations in Brazil. ### Who is Marcio Maciel, founder of Magecore? Marcio Maciel is co-founder of Magecore, a Magento pioneer in Brazil, Meet Magento BR speaker (2012, 2013, and 2017), and winner of the MageHackathon Marketplace at Magento Imagine 2018 in Las Vegas.

Full profile on our About page. ### How long does a zero-downtime platform migration take? 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. ### What is a "precision assessment" and what does it deliver? It is an AI-assisted multidimensional diagnostic that identifies margin leaks and technical debt in Adobe Commerce / Magento operations, delivered in 1 to 3 weeks. The deliverable includes a map of invisible costs, prioritized interventions with financial impact, and a clear recommendation: migrate, optimize, or keep the current platform. ### How much does an initial diagnostic cost? The initial 30-minute conversation and pre-diagnostic with the three main areas of concern are free. The full Precision Assessment is a fixed-scope project; investment varies by operation size and complexity and is presented after the initial conversation. ### How does Magecore use AI in delivery? AI is internal infrastructure for diagnostics, predictive monitoring, and delivery acceleration — not a product sold to the client. We use AI to cross-reference cost, code, and operations data in assessments, detect failure patterns in incidents, and reduce rework in migrations and roadmaps. ### Is it worth migrating from monolithic Adobe Commerce to modular/headless architecture? Yes, when the monolith limits margin, change velocity, or scalability, and migration ROI exceeds the cost of maintaining the status quo. In some cases the assessment shows the platform is not the bottleneck; integrations and infrastructure respond better to optimization. The decision is based on numbers, not tech trends. ### How do you measure ROI on a technical intervention? Every recommendation is tied to client P&L metrics: TCO, conversion, support tickets, LTV, or annual operational savings. We define a baseline before the intervention, a measurement period (typically 12 months), and report documented results — the same criterion used in published case studies. ### Does Magecore work with Mage-OS in addition to Adobe Commerce/Magento? Yes. We operate across Adobe Commerce, Magento Open Source, and Mage-OS with the same diagnostic, migration, and roadmap methodology. Distribution choice depends on licensing requirements, integrations, and the client's long-term strategy, evaluated in the assessment. ### What TCO reduction is realistic to expect? 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. ### How does engagement work: fixed project, retainer, squad? We work with fixed scope per phase: Assessment (1–3 weeks), Engineering (3–6 months), and Sustainment/Roadmap (12 months). We do not sell ad-hoc hours. Each phase has deliverables, timeline, and expected financial outcome defined before kickoff. Dedicated squad models are evaluated case by case after the assessment. ### Do you serve clients outside the Magento ecosystem? Magecore's core is Adobe Commerce / Magento and Mage-OS, where we have over a decade of expertise. For other complex e-commerce platforms, we evaluate fit in the initial diagnostic. The methodology (P&L, AI, modular architecture) applies, but delivery depth is greatest in the ecosystem where we started. --- ## /en/cases # Documented cases ### M1 to Adobe Commerce Cloud migration Operation with significant revenue still on Magento 1.
