The verdict in three sentences
A migration from Magento to a modern stack costs between 50,000 and 150,000 EUR in Amsterdam in 2026, over a 6 to 12 month timeline depending on catalog size and number of integrations. The main risk is not technical but SEO and service continuity: without a rigorous 301 redirect plan, you lose traffic and orders. Done well, migration sharply reduces maintenance and improves performance, two areas where Magento is expensive in 2026.
Why leave Magento and what it costs
Between high maintenance costs, heavy upgrades and end-of-life for some versions (EOL), many CIOs replatform to modern stacks (headless, composable). The budget depends mostly on the volume of data to migrate and the integrations.
| Migration scope | 2026 cost (EUR) | Timeline | SEO risk |
|---|---|---|---|
| Catalog < 5,000 SKUs, simple integrations | 50,000 - 75,000 | 6 - 7 months | Low if redirects OK |
| Catalog 5,000 - 30,000 SKUs, ERP + PIM | 75,000 - 110,000 | 8 - 10 months | Medium |
| Catalog > 30,000 SKUs, EDI, multi-site | 110,000 - 150,000 | 10 - 12 months | High (strict plan needed) |
| Order/customer history migration | + 8,000 - 25,000 | included | N/A |
Cost items and maintenance savings
| Item | Detail | Gain after migration |
|---|---|---|
| Catalog / PIM migration | Cleanup, mapping, media | Clean data, fewer errors |
| Customer / order migration | Accounts, balances, history | Commercial continuity |
| 301 redirects | Exhaustive URL mapping | SEO preservation |
| ERP integration | Stock, prices, balances real-time | Fewer manual entries |
| Annual maintenance | Magento: 15,000 - 40,000 EUR/yr | Modern: 8,000 - 20,000 EUR/yr |
| Performance (Core Web Vitals) | Load time cut by 2-3x | + conversion |
In 2026, annual maintenance of a modern stack is often 40 to 55% below that of an aging Magento.

Karim, CIO of a B2B technical parts distributor in Amsterdam, runs a Magento with 22,000 SKUs and a Sage ERP. His annual maintenance reaches 32,000 EUR and his site loads in 4.8 s. He invests 98,000 EUR in a migration to a modern headless stack.
Result: maintenance cut to 15,000 EUR/year (i.e. 17,000 EUR saved every year), load time down to 1.6 s, and +18% conversion rate thanks to performance. With a rigorous 301 plan, organic traffic is preserved from month 2. The migration cost pays back in about 3 years via the maintenance drop alone, before counting the conversion gain.
