Technical SEO & DNS Redirect Setup: Weebly to Shopify Migration

I am currently migrating my e-commerce store from Weebly to a new Shopify store on a new domain (.com.au). My data migration agent is handling the product import and relative path mapping, but I need an expert to handle the external domain migration, DNS routing, and Cloudflare configuration to protect my legacy SEO. Tasks Required: 1. Configure Cloudflare DNS for both the old domain and the new .com.au domain. 2. Set up bulk permanent 301 redirects to catch legacy Weebly .html URL structures and route them to the new Shopify handles. 3. Ensure the old domain cleanly forwards all traffic to the new primary Shopify domain without causing redirect chains. 4. Verify the setup via Google Search Console and implement the Change of Address tool. Requirements: - Proven experience with technical e-commerce migrations (Weebly/Shopify experience a major plus). - Deep knowledge of Cloudflare Page Rules/Redirect Rules and DNS management. - Strong understanding of Google Search Console protocols.
