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

Yes, the three Sydney migration paths we run most often. Shopify Plus → Magento 2.4.9: 6-10 weeks, Data Migration Tool for products + orders + customers, custom scripts for Shopify metafields + Shopify Scripts + Shopify Functions, Adobe Cloud Sydney or AC3 hosting. Reasons AU brands migrate off Shopify Plus: better B2B (ABN-gated catalogues, Net-30 with BPAY), lower per-transaction fees at scale (no 0.15% Shopify Plus tax above A$800k/year), Hyvä performance (LCP < 1.2s vs Shopify 3s+), control over Afterpay + Zip + eWAY integration depth. BigCommerce → Magento: 5-8 weeks, custom ETL for product attributes + price-list-groups (BigCommerce price-lists map to Magento customer-group prices), 1:1 URL mapping for SEO. Reason: B2B feature ceiling. 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, no security patches. Neto / Maropost Commerce → Magento is a 4th common AU path (since Maropost announced Neto wind-down). URL-preservation 301-redirects are mandatory in all four cases.
