WordPress Migration Services: What to Expect (2026 Guide)

WordPress migration services cover three different jobs that get lumped under one name: moving a site between hosts, moving a site onto WordPress from another platform, and rebuilding an existing WordPress site on new infrastructure. Scope changes the price and timeline more than anything else. Most projects land between $2,000 and $10,000, with a simple host-to-host move costing as little as $300 to $1,500 and a full platform rebuild running higher.

What counts as a WordPress migration

• Host-to-host migration. Same WordPress site, new server. Files, database, and DNS move; the site itself stays the same.
• Platform-to-WordPress migration. Content and structure move from Wix, Squarespace, or a custom CMS into WordPress, usually alongside a design refresh.
• Version or infrastructure rebuild. An aging WordPress install gets rebuilt on current PHP, a modern theme, and a cleaner plugin stack without changing the platform.

What it actually costs

Thousands of SKUs, multilingual content, and custom integrations push any of these ranges toward the top. A simple five-page brochure site can migrate for a few hundred dollars in an afternoon; a store with a decade of content and a dozen integrations cannot.

The process, step by step

• Audit and backup. A full backup of files, database, and media before anything moves, plus an inventory of plugins, integrations, and custom code.
• Staging build. The new site gets built on a staging URL nobody but the team can see, so testing happens without risking the live site.
• Content and data transfer. Pages, posts, products, users, and media move over, checked against the original for anything that broke in transit.
• Redirect mapping. Every old URL that changes gets a 301 redirect, so search rankings and inbound links carry over instead of hitting a 404.
• Testing. Forms, checkout, search, and page speed get tested on staging before the domain points anywhere new.
• Cutover and monitoring. DNS switches over during low-traffic hours, then the team watches uptime, forms, and analytics for the first one to two weeks.

Why downtime matters more than speed

A rushed migration that skips staging can take a site offline for hours while problems get fixed live. For a small business, downtime costs run $100 to $5,000 an hour depending on how much revenue and traffic the site carries. A staging-first process costs a little more time up front and removes most of that risk.

What to ask before you hire a migration service

• Do you build on staging first, or work directly on the live site?
• Who owns the redirect map, and how do you handle URLs that change?
• What happens if the migration uncovers a broken plugin or undocumented custom code?
• What's included after launch: a monitoring window, a fixed number of revision rounds, or neither?

A migration service that cannot answer these clearly is not ready to touch a live site. Our guide on questions to ask before hiring an offshore agency covers the broader vetting process if the work is going to an outside team.

A paid migration earns its cost when the site carries real traffic, revenue, or SEO equity worth protecting, since that equity is exactly what a rushed DIY move puts at risk. For a brochure site with a handful of pages, a careful DIY move on a quiet weekend is reasonable. For anything with an active store, meaningful organic traffic, or forms feeding a sales pipeline, the redirect mapping and staging discipline above are worth paying for. We handle WordPress migrations as part of our WordPress development work, and if the move is really a visual refresh rather than a platform change, our WordPress site redesign checklist is the better starting point.
