The verdict in three sentences
Migrating an ageing Magento 2 to headless commerce costs, in 2026, between 45,000 and 80,000 EUR, versus 15,000 to 30,000 EUR/year of Magento maintenance that the migration durably reduces. The three batches — audit + data migration, Next.js/Vue Storefront front, checkout/payment re-implementation — ship in 4 to 6 months. ROI comes from performance: LCP cut by 40 to 60 %, mobile conversion up 10 to 25 %.
The cost per batch in 2026
A headless migration often keeps Magento as the back office (data source) but replaces the entire front end with a modern, fast layer. Here is the breakdown.
| Batch | Scope | 2026 range (EUR) |
|---|---|---|
| Audit + data migration | Catalogue, customers, orders, SEO redirects | 8,000 - 15,000 |
| Headless front (Next.js / Vue Storefront) | PLP, PDP, search, cart, PWA | 25,000 - 45,000 |
| Checkout / payment re-implementation | Funnel, PSP, tax, shipping | 10,000 - 18,000 |
| QA, SEO, go-live | Testing, 301s, monitoring | 5,000 - 10,000 |
| Total migration | 48,000 - 80,000 |
Data migration and 301 redirects are critical: a poorly handled migration crashes rankings. This is where a provider's experience shows the most.
What the migration wins you
The cost is justified by measurable gains, in performance as in operations.
| Metric | Magento 2 (before) | Headless (after) | Gain |
|---|---|---|---|
| Mobile LCP | 4.2 s | 1.8 s | -57 % |
| Mobile conversion rate | 1.4 % | 1.7 - 1.9 % | +20 % to +35 % |
| Annual hosting cost | 12,000 - 20,000 | 4,000 - 8,000 | -50 % to -60 % |
| Annual maintenance cost | 15,000 - 30,000 | 8,000 - 16,000 | -45 % |
Recurring hosting and maintenance savings alone amortise part of the project; the conversion uplift acts directly on revenue.

Mini case study
Karim, e-commerce manager of an auto-parts site in Dubai, does 1.8M EUR GMV with 65 % mobile traffic converting at 1.4 %. Moving to 1.75 % post-migration, the mobile rate rises 25 %, i.e. about +290,000 EUR GMV/year at constant basket. He also pays -9,000 EUR/year hosting and -10,000 EUR/year maintenance. On a 62,000 EUR migration, payback is reached in under 9 months counting only margin on the extra sales.
FAQ
Must Magento be dropped entirely? Not necessarily: in headless, you can keep Magento as the back office and replace only the front. This reduces the risk and cost of the first phase.
What's the SEO risk of a migration? Real but manageable: a thorough 301 redirect plan and clean URL mapping prevent the drop. That's why the initial audit (8,000-15,000 EUR) is non-negotiable.
How long should we plan? 4 to 6 months depending on catalogue size and integrations (ERP, PIM, carriers). A freeze on Magento changes during the switch is recommended.
Why is Magento so expensive to maintain? Heavy version upgrades, security, resource-hungry hosting and rare skills: 15,000 to 30,000 EUR/year is common. Headless durably lightens this load.
Vue Storefront or custom Next.js? Vue Storefront speeds up start on a proven base; custom Next.js offers more freedom. The choice depends on your functional specifics and your team.
