Website Migration Services | Platform, Hosting, Domain and CMS Migrations Without Losing SEO

Updated September 2026 · Written and maintained by the Progression Agency strategy team

Progression Agency provides website migration services: moving sites between platforms (WordPress, Webflow, Shopify, Next.js, Astro, HubSpot, Squarespace, Wix), between hosts, to new domains or new designs, with content, redirects, tracking and search rankings preserved. A site migration service earns its fee on the parts a visitor never sees, and a web site migration that looks finished on launch day can still lose traffic for weeks. Choosing a website migration company mostly means finding a website migration expert who treats redirects, tracking and rankings as part of the build rather than as cleanup after launch.

What do website migration services include?

A full inventory of the existing site; a migration plan covering platform, hosting, URLs and redirects; migration of content, media, metadata and users; rebuilding of templates and features; re-implementation of forms, tracking and integrations; staging tests; the DNS switch; and post-launch monitoring of indexing, rankings, errors and performance until the site is stable.

Common migrations we run: WordPress to Webflow or Next.js, Wix or Squarespace to WordPress, Magento or WooCommerce to Shopify, Gatsby or Create React App to Next.js, shared hosting to managed hosting, and domain changes after rebranding. See WordPress alternatives and hosting types compared.

The process follows Google’s guidance on site moves with URL changes and redirects.

Website migration services

Projects we are most often asked to build.

Platform and CMS migrations

WordPress to Webflow, Next.js or Astro; Wix, Squarespace or HubSpot to WordPress; Drupal to WordPress; legacy CMS to headless; see best CMS platforms.

Ecommerce platform migrations

Magento, BigCommerce, WooCommerce or custom stores to Shopify, or Shopify to WooCommerce, with products, customers, orders and redirects; see ecommerce redesign.

Hosting migrations

Shared hosting to managed WordPress hosting, Heroku to Render or AWS, on-premises to cloud, with zero or minimal downtime; see WordPress hosting guide and cloud migration services. A web hosting migration changes where the site lives without changing what visitors see, so the real work is matching server settings, copying databases cleanly and testing the new host before DNS moves.

Domain and URL structure migrations

Rebrands, domain consolidations, HTTP to HTTPS, subdomain to subfolder, with redirect rules and Search Console change-of-address.

Framework migrations

Gatsby, Create React App, AngularJS or jQuery sites to Next.js or Astro; see Next.js development.

Migration recovery

Diagnosing and repairing traffic loss after a migration done elsewhere: missing redirects, dropped content, crawl errors, speed regressions.

Key features and components

What separates a useful build from a costly one. Website content migration is where most hidden hours sit, since old pages rarely fit new templates cleanly. On a content migration website project, decide early what gets moved, merged or rewritten. A plain website transfer service that only copies files covers none of that.

Common integrations

Where the value usually comes from.

SEO safeguards during migration

A migration is successful only if organic traffic is the same or better ninety days later. That is why SEO for website redesign and migration starts before launch, with a crawl of the old URLs, a redirect map and a baseline to compare against afterward. Site migration and SEO belong in one plan, because URL decisions get made early in design. An SEO migration service working beside the build team can review those decisions before they harden. Buying SEO migration services separately? Then give the SEO migration agency staging access and a say over launch timing.

• Every old URL is crawled and mapped to a new URL with a 301 redirect, avoiding chains and loops, per Google’s redirect guidance.
• Titles, meta descriptions, headings, canonical tags and schema.org structured data are preserved or improved, never dropped.
• XML sitemaps are regenerated and submitted; Search Console change-of-address is used for domain moves.
• Speed is measured against Core Web Vitals on staging and after launch, because a slower site loses rankings even with perfect redirects.

A site migration checklist and project plan

A website migration project plan needs four things a task list lacks: a named owner for every line, a freeze date for content edits, a rollback trigger and a go or no-go meeting before DNS changes. The site migration SEO checklist sits inside it and starts with exporting benchmarks, since nothing can be compared after launch without them.

Starting from a website migration plan template is fine, provided you strike what does not apply and add what is particular to your site: subdomains, PDFs, language versions, gated forms. A site migration checklist should run until ninety days after launch rather than stopping at go-live.

Our website migration process

We crawl and inventory the current site, plan the target platform and URL map, migrate content and integrations, rebuild templates, test on staging, switch DNS at a quiet time with redirects live, and monitor indexing and rankings for ninety days. Those website migration steps run in a deliberate order because each one protects the next: the crawl feeds the URL map, the URL map feeds the redirects, and the redirects must be live before DNS changes.

How much do website migration services cost?

As US price figures: hosting migrations $1,000-$5,000; domain or URL-structure migrations $2,000-$10,000; platform migrations for business sites $8,000-$60,000; ecommerce platform migrations $15,000-$80,000; large content or enterprise migrations $50,000 and up.

Website migration service cost: what changes the price

A handful of factors, not the brand of the new platform, decide website migration service cost. The number of pages and templates to rebuild or map, how much content needs cleanup, the number of redirects to plan and test, integrations that must be reconnected, the amount of tracking to rebuild and any requirement for little or no downtime all move the figure. Moving to a new host with the same platform is the lightest case, while changing CMS, domain and URL structure at once is the heaviest. Ask for a quote that lists the redirect plan, the testing steps and the post-launch monitoring as separate lines, so you can see what is included. If hosting is part of the move, our website hosting cost guide explains what the destination will cost to run.

Technology we typically use

Mainstream, maintainable choices.

When a WordPress website migration plugin is safe, and when it is not

A WordPress site migration between hosts, with the same domain and the same URLs, is where a plugin does well. Duplicator and All-in-One WP Migration both package a site into a single file and restore it on the new server. Small brochure sites are the natural fit, because a site migration WordPress owners can rehearse on staging carries little risk.

The risk rises with size and activity. Your host may limit how large a file you can upload, a store keeps taking orders while the copy runs, and multisite networks need checking separately. In those cases a site migration WordPress plugin is the wrong starting point, so we copy at server level with scripts. Changing the domain also means rewriting URLs in the database, and the WP-CLI search-replace command handles the PHP serialized data that a plain text swap would corrupt.

No website migration tool writes your redirect map or decides which pages stay. Crawlers and importers are website migration tools that speed up the labor. Judge any site migration tool by what it lets you verify afterward, not by how fast it moves files.

Mistakes to avoid

Common causes of overruns and low adoption.

• Changing URLs without a redirect map.
• Dropping thin pages that were ranking.
• Launching a slower site than the old one.
• Forgetting email DNS records during a domain move.
• Switching DNS at peak hours.
• Stopping monitoring the day after launch.
