Can you migrate from Shopify Plus / WooCommerce / Magento 1 to Magento 2.4.9?

Yes, the three London migration paths we run weekly. Shopify Plus → Magento 2.4.9: 6-10 weeks, Data Migration Tool for products + orders + customers, custom scripts for metafields + Shopify apps, AWS eu-west-2 or Adobe Cloud Dublin hosting. Reasons: better B2B, lower per-transaction fees at scale (no 0.15% Shopify Plus tax), Hyvä performance. WooCommerce → Magento: 8-12 weeks, custom ETL for product attributes (WooCommerce schema is looser than Magento's EAV), 1:1 URL mapping for SEO, ACF custom fields mapped to product attributes. Reason: scale, WooCommerce struggles past 50k SKUs / £5M GMV. Magento 1 → Magento 2.4.9: 10-16 weeks, official Data Migration Tool + extension audit (M1 extensions don't port), Hyvä theme rebuild. Reason: M1 is EOL since June 2020, PCI-DSS non-compliant. URL-preservation 301-redirects are mandatory in all three cases.
