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

Yes, the three most-common LA-DTC migration paths we run. Shopify Plus → Magento 2.4.9: 6-10 weeks, Data Migration Tool for products + orders + customers, custom scripts for Shopify metafields + Shopify apps (Klaviyo / Yotpo / Recharge / Loop Returns), Shop Pay vault transferred via Stripe Issuing if applicable. Reasons LA brands migrate: better B2B (DTLA Fashion wholesale), lower per-transaction fees at scale (no 0.15% Shopify Plus tax once you cross $5M GMV), Hyvä performance, better SEO control. Shopify (non-Plus) → Magento: 4-8 weeks, simpler since fewer custom apps to port. Magento 1 → Magento 2.4.9: 10-16 weeks, official Data Migration Tool + extension audit (M1 extensions don't port), Hyvä theme rebuild. M1 is EOL since June 2020, PCI-DSS non-compliant, if you're still on M1, the migration is urgent. URL-preservation 301-redirects are mandatory for SEO retention in all three cases. We do a 2-week SEO-monitoring window post-cutover and fix any traffic drops.
