I need to move twenty active e-commerce websites from our current host to a new server without any interruption to customers. We will handle the transition in clearly defined phases so each store can be tested, switched, and monitored before the next one is touched. After every domain goes live on the new environment, you will stay on as the point person for routine maintenance, uptime monitoring, security patching, and quick-response troubleshooting so none of the sites ever go down. Here is how I see the work flowing: • Phase-by-phase migration: full file and database transfer, SSL re-issuance, DNS cut-over, and final verification for each store before moving to the next. • Post-migration stewardship: continuous uptime checks, platform updates, backup management, and emergency support with clear response times. These shops run typical e-commerce stacks—cPanel/WHM, MySQL, PHP, and a mix of WordPress + WooCommerce and a few custom carts—so familiarity with those tools plus CDN tuning (Cloudflare), staging workflows, and server-level security hardening will be valuable. When you respond, keep it simple: outline your relevant experience handling multi-site e-commerce migrations and ongoing maintenance. If that background is clear, we can jump straight into timelines and access details. Please quote the price you want to charge upfront as changes in quotes won't be accepted.
