WordPress to Next.js Migration: What It Actually Takes

Migrating from WordPress to Next.js takes 8–16 weeks and costs $25,000–$65,000 for most business sites. The range is wide because the complexity varies enormously depending on how customized your WordPress install is, how many pages you have, and what functionality needs to be rebuilt or replaced.

Here is what actually happens during a migration, what tends to go wrong, and how to evaluate whether the move is worth it.

Why businesses make the move

WordPress powers a large share of business websites, but it accumulates technical debt. Plugins conflict. Performance degrades. Page builders lock content into proprietary formats. Security patches require ongoing attention. And critically, WordPress's architecture makes it genuinely difficult to build the kind of custom features — quote builders, CRM integrations, AI assistants — that growing businesses need.

Next.js on Vercel is fast by default, generates static pages that load in under a second, handles thousands of pages without performance degradation, and integrates cleanly with any database or API. For businesses that have outgrown WordPress, the move pays off in performance, security posture, and the ability to build custom functionality without fighting the platform.

What a real migration involves

Content audit and inventory

The first step is understanding exactly what you have. Every page, every post, every custom post type, every piece of media. For a 283-page site — the scale of Golf The High Sierra, which we migrated — this is a full audit, not a quick count.

Some content migrates cleanly as Markdown or MDX. Some content is locked into page builder formats (Elementor, Divi, WPBakery) that have to be rebuilt by hand. This is often the most time-consuming part of the migration, and it's the part most agencies underestimate.

Redirects

Every URL that exists in Google's index needs to either stay the same or receive a permanent 301 redirect to its new location. Missing redirects mean lost SEO authority that took years to build. A 283-page site has at minimum 283 redirects to map — often more if the URL structure is changing.

This step requires exporting your current URL list from Google Search Console, mapping every URL to its destination, and implementing the redirects before the new site goes live.

Custom functionality rebuild

WordPress plugins that handle forms, booking, payments, galleries, and other functionality need to be replaced. Sometimes with better custom code, sometimes with API integrations, sometimes with third-party services. Each plugin that gets replaced is a scope item with its own estimate.

The common mistake: treating plugin replacement as trivial because "there's a package for that." There often is. It still takes time to integrate, test, and connect to your data.

SEO continuity

Page titles, meta descriptions, schema markup, canonical URLs, XML sitemap — all of these need to be rebuilt in the new system and verified after launch. WordPress SEO plugins (Yoast, RankMath) do a lot of this work implicitly. In Next.js, you build it explicitly. That's actually better because you have full control, but it requires deliberate work.

Launch sequencing

A proper migration launches with zero downtime. The process: build on a staging URL, test thoroughly, run a pre-launch SEO audit, cut DNS over to the new site, verify redirects are working, submit the new sitemap to Google Search Console. The window where both sites exist simultaneously should be as short as possible.

What tends to go wrong

Underestimating content that's locked in page builders. Elementor content in particular has to be rebuilt page by page. There's no clean export. If you have 100 pages built in Elementor, budget for 100 pages of manual rebuild work.

Missing redirects for paginated URLs. WordPress often generates paginated versions of category pages, archive pages, and blog indices. These URLs can be indexed. Missing the redirects loses that authority.

Plugin functionality that was more complex than it appeared. A booking plugin or a form with conditional logic often has months of configuration built up inside it. Replacing it requires understanding exactly what it was doing, not just what it looked like on the surface.

DNS propagation timing. DNS changes take time to propagate globally. If you cut over at the wrong time, users in some locations see the old site while others see the new one. Coordinate cutover for low-traffic periods.

When the migration is worth it

The move makes financial sense when:

Your WordPress site is slow (Core Web Vitals failing, PageSpeed under 50 on mobile)
You need custom functionality that plugins can't provide cleanly
Security maintenance is consuming significant time or has caused incidents
You're planning to build an AI integration, booking system, or CRM that needs a real backend
SEO performance is being limited by technical debt

The move is not worth it when:

Your WordPress site is working well and you mainly want a visual refresh
You don't have custom functionality requirements
You don't have budget to do it properly — a rushed migration is worse than staying on WordPress

Our migration experience

The Golf The High Sierra migration moved 283 WordPress pages to Next.js with zero downtime. Every URL was preserved or redirected. Every piece of content was rebuilt — including complex course and property pages that had been built in a page builder over several years. The new site added a quote system, CRM, and AI trip planner that didn't exist in the WordPress version.

BRE Builders is currently in the same process — WordPress live, Next.js staging on Vercel, with a Gmail-integrated photo upload system added that would have been impossible to build cleanly in WordPress.
