eCommerce Migration Services and Replatforming Agency

Most mid-market migrations land between $15,000 and $50,000. Small-catalog Shopify-to-Shopify moves can start around $5,000, and complex enterprise replatforms with custom integrations, large catalogs, and multi-store setups run $150,000 and up. The biggest cost drivers are catalog size, custom functionality, and the number of integrated systems. Optimum7 gives you a fixed scope and price before the project starts.

A standard mid-market migration takes 6 to 12 weeks from kickoff to launch. Catalogs under 500 products can be ready in 4 to 6 weeks. Enterprise migrations with custom functionality, large catalogs, or multiple integrations run 4 to 6 months. Every project includes a fixed timeline as part of the plan.

Not if the migration is done correctly. Most post-migration ranking drops come from broken redirects, lost metadata, or changed URL structures. Our process preserves every 301 redirect, page title, meta description, image alt text, structured data element, and canonical tag, which is why our migrations typically hold or improve organic traffic within 30 to 90 days.

Every old URL gets a one-to-one 301 redirect to its new location in a single hop. We map them from a full crawl of your live site and prioritize any URL with recent organic traffic, so links, rankings, and bookmarks keep working after the move.

Accounts, order history, and customer groups move across. Passwords are stored as one-way hashes that cannot be transferred between platforms, so customers set a new password through a secure reset on their first login. You keep every customer record.

A clean migration usually holds traffic through launch. When there is a temporary dip, most stores recover to baseline within 30 to 90 days, and faster when redirects and metadata are handled correctly from day one.

The new store is built and fully tested before go-live, so the switch itself is fast. Any downtime is planned, kept short, and scheduled for low-traffic windows, and you know the exact window in advance.

A complete migration includes platform setup, theme migration or redesign, full data migration of products, customers, orders, and reviews, custom functionality rebuilds, third-party integrations, payment gateway configuration, SEO preservation covering redirects, metadata, and structured data, pre-launch QA, post-launch monitoring, and team training on the new platform.

Yes. Every migration starts with a pre-migration SEO baseline covering rankings, traffic, indexed URLs, and backlink profile, then runs post-migration audits at 7, 30, and 90 days. We monitor for indexation issues, broken redirects, ranking drops, and crawl errors, and resolve them within the migration warranty period at no extra cost.

A well-planned migration is low risk and often improves site speed, functionality, and conversions. The risk comes from poor planning: data loss, broken redirects, incompatible apps, and design that does not carry over. Working with a team that runs a proven process and sets up 301 redirects protects your SEO value and your revenue during the move.

Optimum7 migrates between every major platform, including Shopify, Shopify Plus, BigCommerce, Magento, WooCommerce, Volusion, Wix, Salesforce Commerce Cloud, SAP Hybris, VTEX, Miva, OpenCart, and custom carts. We build an individual migration plan for your source and target platform.

Look for a team that names its SEO-preservation method, including 301 mapping, metadata carryover, and staged cutover, has migrated your specific platform pair before, rebuilds custom functionality instead of dropping it, and monitors traffic after launch. Ask for case studies with real post-migration results.

Optimum7 offers a Free Migration Evaluation: we review your current store, catalog, integrations, and goals, then recommend a target platform and scope. There is no commitment. After the evaluation you can move ahead with a full data migration or replatforming project.
