Nathan, 34 migrations. What's the failure mode that appears most often?G
Nathan Okafor0:00
Ignoring URL redirects until two weeks before launch. You spend nine months on product data and customer records and then someone says 'oh we should probably do the redirects' when you're days from going live. Fifty thousand products, each with a Magento URL that Google has indexed, and you're mapping them in a spreadsheet under pressure. That's how you lose 40% of your organic traffic on day one and spend six months wondering what happened.H

Tell me about the Magento configurable/simple product model and why it's such a headache to map to Shopify.G
Nathan Okafor13:45
Magento has a two-layer model. The configurable product is the parent — 'Blue Widget' — and it has 12 simple products as children, one per size/color combination. Each simple product has its own SKU, URL, inventory, and sometimes its own images and description. Shopify's model is flat: one product with up to 100 variants. So you have to decide — do you map the configurable to a Shopify product? Do you keep child SKUs? What happens to the child URLs? There's no universal answer, and the wrong decision creates SEO and inventory management problems for years.H

The customer password problem. You can't import hashed Magento passwords into Shopify. How do you handle that without forcing 100,000 customers to reset their passwords on day one?G
Nathan Okafor18:30
The best UX we've found is a lazy migration. You import all customer accounts without passwords. On their first login to the new store, you show a 'please set your password for our new site' screen. You don't call it a reset — you frame it as a security upgrade for the new platform. And you send an email sequence pre-launch that explains there's an exciting new shopping experience coming. Framing matters. Done right, 70–80% of active customers migrate their account in the first 30 days.H

What's the migration mistake that's impossible to undo?G
Nathan Okafor62:00
Deleting the Magento store before you've validated the redirects are working in Shopify and confirmed Google is recrawling. We had one client shut down Magento hosting the day of cutover to save costs. Three days later they noticed their top 200 product URLs were returning 404s in Search Console because a batch of redirects hadn't imported correctly. The Magento store was gone. We had to reconstruct the URL list from crawl data and Search Console exports. It took four months to recover the rankings. Keep Magento on a cheap VPS for 90 days minimum after cutover.Let's ship something great
