Migrating from WooCommerce to Magento — timeline + cost?

Well-trodden path. Realistic numbers for a typical Woo store at 5k–15k SKUs:

• Timeline: 6–12 weeks for a clean Hyvä-themed Magento rebuild, including data import. Faster (4 weeks) for sub-1k SKUs with a stock theme; longer (16+ weeks) if you’re also re-platforming PIM / ERP or have heavy Woo customisations.
• Cost: $12k–$50k for the rebuild + data migration. Tools like cart2cart ($300–$1.2k) handle the bulk product/customer/order transfer; the rest is dev time on theme / payments / shipping / SEO redirects.
• What breaks: (1) WP-specific URL patterns don’t map 1:1 to Magento — you need 301-redirect maps for every product/category, (2) WP user passwords are bcrypt with a different salt, so users have to reset on first login, (3) Yoast SEO meta migrates only if you use a custom mapping plugin, (4) pretty permalink slugs in WP often clash with Magento’s URL rewrite logic.

The migration is more about SEO continuity than tech. Map redirects for every indexed URL, run both stores parallel for 30 days behind a feature flag, validate the redirect map covers ≥98% of organic traffic, then cut DNS.
