Drupal to Next.js migrations typically cost £12,000-£30,000 ($15,000-$40,000) for a small site. Medium sites cost £30,000-£75,000 ($40,000-$95,000). Enterprise builds cost £75,000-£200,000+ ($95,000-$250,000+). Final price depends on content volume, custom functionality, integrations, editorial workflow needs, and how much SEO equity you need to keep.

Key takeaways

  • Small Drupal sites (10-50 pages) run £12,000-£30,000 / $15,000-$40,000. Enterprise migrations can exceed £200,000 / $250,000.
  • Content migration, mapping Paragraphs, media libraries, and URL redirects, is the most common source of budget overruns.
  • UK agency day rates tend to run a bit lower than US hourly rates. London enterprise agencies often match US pricing, though.
  • Drupal 7's end of life and a shrinking Drupal developer pool are the main drivers behind 2026 migrations.
  • Supabase-backed architecture can lower long-term hosting costs. But it usually means building a custom admin panel from scratch.

Drupal to Next.js Migration Cost in 2026: Real Pricing in GBP & USD

Why Drupal Sites Are Migrating Now

Drupal 7 reached end-of-life in January 2025. That was the big trigger. Thousands of organisations, especially in UK government, higher education, and enterprise, were running on D7. They suddenly faced a choice: upgrade to Drupal 10/11, or jump ship entirely.

Here's the thing. If you're going to rebuild anyway, a lot of teams question whether Drupal is still the right platform. The Drupal developer pool has been shrinking since 2020. Contributor activity has also dropped compared to a few years ago. Meanwhile, the JavaScript ecosystem keeps growing.

For many organisations, moving to a headless setup with Next.js makes more sense than another Drupal-to-Drupal upgrade. That upgrade would just repeat the same painful process again in five years.

That said, this isn't a "Drupal is dead" article. Drupal 11 is solid. But the economics have shifted. That's what we're here to talk about.

The Real Cost Factors

Before diving into numbers, it helps to know what drives the cost of a Drupal-to-Next.js migration. These are the variables behind that massive spread in quotes.

Content Volume and Structure

A brochure site with 50 pages is very different from a publishing platform with 40,000 articles, custom taxonomies, and paragraph-based layouts. Mapping the content model alone can take weeks on larger sites.

Custom Functionality

Every custom Drupal module needs an equivalent. Some are simple, like a contact form. Some are costly, like a custom booking system built on Drupal entities. If you've got Drupal Commerce, add 30-40% to your budget.

Integration Complexity

CRMs, payment gateways, SSO providers, legacy APIs. Each one needs to be rebuilt or adapted. Some Drupal sites look simple on their own but connect to seven or more external systems, and each needs new integration work.

Editorial Workflow Requirements

Drupal's content moderation and workflow system is genuinely good. Copying that in a headless CMS takes real effort. If your editors rely on complex approval chains, this adds cost.

SEO Preservation

If your site gets solid organic traffic, keeping URL structures, redirects, metadata, and structured data is a must. This is often underestimated. A site with 10,000+ indexed pages needs a carefully planned redirect strategy.

Accessibility and Compliance

UK public sector sites need WCAG 2.2 AA compliance. US sites increasingly need it too, especially after the 2024 DOJ ruling on web accessibility. Building an accessible Next.js frontend from scratch costs more than using Drupal's tested contrib themes.

Pricing by Site Complexity

Here's where we get concrete. These ranges show typical UK and US agency pricing for migrations of this scope, based on current market rates through 2025 and into 2026. They assume a professional agency engagement, not a solo freelancer.

Site Complexity Description UK Agency Cost (GBP) US Agency Cost (USD) Timeline
Small 10-50 pages, blog, contact forms, basic CMS £12,000 - £30,000 $15,000 - $40,000 6-10 weeks
Medium 50-500 pages, multiple content types, search, integrations £30,000 - £75,000 $40,000 - $95,000 10-18 weeks
Large / Enterprise 500-10,000+ pages, complex workflows, e-commerce, multilingual, multiple integrations £75,000 - £200,000+ $95,000 - $250,000+ 4-9 months
Government / Public Sector Accessibility requirements, security audit, GDS compliance £50,000 - £150,000 $65,000 - $180,000 3-8 months

A few notes on these numbers:

  • The low end of each range assumes a simple content migration with a standard design system. The high end assumes custom design, complex data migration, and multiple integrations.
  • Enterprise quotes above £100k/$125k usually include a discovery phase, content strategy, and post-launch support contract.
  • These don't include ongoing hosting and maintenance costs, which we cover in the TCO section.

Drupal to Next.js Migration Cost in 2026: Real Pricing in GBP & USD - architecture

Agency Rates: UK vs US in 2026

The rate gap between UK and US agencies has narrowed in recent years. It's still notable, though. Here's what you're looking at for blended rates (the average across different roles on the project):

Role UK Day Rate (GBP) US Hourly Rate (USD)
Senior Next.js Developer £500 - £800/day $150 - $250/hr
Mid-level Developer £350 - £550/day $100 - $175/hr
Technical Architect £700 - £1,100/day $175 - $300/hr
UX/UI Designer £400 - £700/day $120 - $200/hr
Project Manager £350 - £600/day $100 - $175/hr
QA Engineer £300 - £500/day $90 - $150/hr
Content Migration Specialist £300 - £500/day $85 - $140/hr

UK agencies typically quote day rates. US agencies typically quote hourly. The UK market tends to be cheaper on average. But London-based agencies with enterprise clients often match or beat US pricing.

Nearshore and offshore options exist too. Eastern European agencies (Poland, Ukraine, Romania) quote £250-£450/day for senior developers. Indian agencies range from £100-£250/day. Quality varies a lot here, so thorough vetting and a trial engagement are worth it before you commit to a full migration.

At Social Animal, our blended rates for Next.js projects sit in the mid-to-upper UK range. This reflects our team's seniority and the architectural complexity of builds like the SleepDr.com migration and the Not Another Sunday directory platform.

Content Migration: The Hidden Money Pit

This is where budget overruns happen most often.

Drupal stores content in a way that's uniquely Drupal. If you've used Paragraphs or Layout Builder, your content sits deeply nested in entity references. A single "page" might actually be 15 different paragraph entities with their own fields, media references, and revision history.

Moving this content to a headless CMS requires:

1. Content Model Mapping

You need to map every Drupal content type, field, taxonomy, and paragraph type to your new CMS structure. This is design work, not just technical work. It's your chance to simplify and clean up years of built-up content clutter.

2. Migration Scripts

Someone needs to write scripts that pull content from Drupal's database (or JSON:API/GraphQL endpoints) and push it into the new CMS. For a site with custom paragraph types, this gets complex fast.

## Simplified example: extracting Drupal paragraphs via JSON:API
import requests

def extract_paragraph_content(node_id, drupal_base_url):
    response = requests.get(
        f"{drupal_base_url}/jsonapi/node/article/{node_id}"
        "?include=field_paragraphs,field_paragraphs.field_image",
        headers={"Accept": "application/vnd.api+json"}
    )
    data = response.json()
    
    paragraphs = []
    for item in data.get("included", []):
        if item["type"].startswith("paragraph--"):
            paragraphs.append({
                "type": item["type"].replace("paragraph--", ""),
                "fields": item["attributes"],
                "relationships": item.get("relationships", {})
            })
    
    return paragraphs

In reality, this gets much messier. You'll deal with embedded media, internal links that need URL remapping, and WYSIWYG content with Drupal-specific markup. Thousands of files may also need to move to a new asset pipeline.

3. Media Migration

Drupal's media system stores files in sites/default/files with its own path structure. Every image, document, and video needs to move to your new hosting (S3, Cloudinary, whatever) with all references updated. For a site with 5,000+ media items, this alone can cost £3,000-£8,000 / $4,000-$10,000.

4. URL Redirects

If your Drupal site used Pathauto (most do), you've got a URL structure that search engines know and trust. You need a full redirect map. For large sites, this means pulling every URL alias from Drupal and building matching redirects in your Next.js app.

// next.config.js redirect example (for smaller sites)
const nextConfig = {
  async redirects() {
    // For large sites, load from a database or JSON file
    const drupalRedirects = await loadRedirectMap();
    return drupalRedirects.map(({ source, destination }) => ({
      source,
      destination,
      permanent: true, // 301 redirect
    }));
  },
};

For enterprise sites with 10,000+ URLs, use middleware-level redirects or an edge function approach. This avoids bloating your Next.js config.

The Developer Shortage Problem

Here's something that hits your budget directly: finding developers who know both Drupal and modern headless architecture is genuinely hard in 2026.

The Drupal talent pool peaked around 2018-2019. Since then, many senior Drupal developers have moved to other frameworks or into management roles. Recent developer surveys show Drupal usage dropping sharply since 2020, while frameworks like Next.js keep gaining ground.

Meanwhile, Next.js developers are plentiful but rarely know Drupal. This creates a skills gap right where you need it most: the migration itself. You need someone who truly understands Drupal's data model to properly pull and transform content.

This shortage drives costs up in two ways:

  1. Drupal migration specialists command premium rates. A developer who can write Drupal migration scripts and design the Next.js destination bills £700-£900/day in the UK.
  2. Projects take longer when the team needs to reverse-engineer an unfamiliar Drupal setup. If nobody on the team has worked with Paragraphs or Layout Builder before, expect a 2-3 week learning curve.

This is one area where working with a specialist headless CMS development agency pays for itself fast.

Headless CMS + Supabase: An Alternative Architecture

Many Drupal-to-Next.js migrations assume you'll swap Drupal for another headless CMS: Sanity, Contentful, Storyblok, or even Drupal itself run headless. But there's a growing alternative: using Supabase as your backend.

Supabase gives you a Postgres database, authentication, file storage, and auto-generated APIs. For teams that want more control over their data model without the limits of a traditional CMS, it's a strong option.

When Supabase Makes Sense

  • Your content is heavily structured/relational (product catalogs, directories, data-heavy applications)
  • You need custom user authentication and role-based access
  • Your editorial team is small and developer-savvy (or you'll build a custom admin UI)
  • You want full ownership of your data infrastructure

When a Traditional Headless CMS is Better

  • Your editorial team is non-technical and needs a polished content editing experience
  • You have complex content workflows with approval chains
  • Content preview and visual editing matter to you
  • You want to get up and running faster

Cost Comparison: Headless CMS vs Supabase

Factor Headless CMS (e.g., Sanity) Supabase
Platform cost (annual) £0 - £12,000+ £0 - £3,000
Content editor UX Excellent out of the box Requires custom admin panel
Custom admin panel development Not needed £8,000 - £25,000
API development Included Auto-generated + custom
Authentication Third-party needed Built-in
File storage Included (CDN) Included (S3-compatible)
Real-time features Limited Built-in
Lock-in risk Medium (proprietary APIs) Low (standard Postgres)

The irony is that Supabase can cost less long-term but more upfront, since you build the editorial experience from scratch. For content-heavy sites migrating from Drupal, a traditional headless CMS usually makes more sense. For application-heavy sites, Supabase is worth a serious look.

We've built both types of setup: a Payload CMS platform for SleepDr.com, and Supabase-driven platforms for Not Another Sunday and Florida Massage Elite. The latter was built in five weeks with Stripe Identity verification. Our Next.js development capability covers both headless CMS integrations and custom Supabase backends.

Total Cost of Ownership: Drupal vs Next.js (5-Year Comparison)

The migration cost is a one-time hit. What matters more for most organisations is the ongoing cost. Here's a realistic 5-year TCO comparison for a medium-complexity site.

Cost Category Drupal (Traditional) Next.js + Headless CMS
Initial build/migration £0 (already built) £40,000 - £75,000
Hosting (annual) £3,000 - £8,000 (dedicated/managed) £600 - £2,400 (Vercel/Netlify)
CMS platform (annual) £0 (open source) £0 - £6,000 (depends on CMS)
Security updates (annual) £4,000 - £10,000 £1,000 - £3,000
Feature development (annual) £8,000 - £20,000 £6,000 - £15,000
Drupal upgrades (per major version) £8,000 - £25,000 N/A
Performance optimization £2,000 - £5,000/year £500 - £2,000/year
5-Year Total £85,000 - £240,000 £78,000 - £177,000

A few things stand out:

Hosting is much cheaper. A Next.js site on Vercel costs a fraction of managed Drupal hosting. Drupal needs PHP, a database server, caching layers (Varnish, Redis), and a lot more compute. A statically-generated or ISR Next.js site can run on edge infrastructure for very little.

Security maintenance costs less too. Drupal's security team is good, but every security advisory means someone must apply patches, test, and deploy. A headless frontend with a managed CMS has a much smaller attack surface.

Developer costs are where it evens out. Next.js developers are easier to find, but the ecosystem moves fast. You'll spend time keeping up with Next.js versions, React updates, and framework changes. The good news: the talent pool is large enough that you won't be held hostage by a single specialist.

The breakeven point for most medium-complexity sites lands around 18-30 months after migration, depending on your current Drupal hosting and maintenance costs.

Timeline Expectations

Every agency gives you a timeline during the sales process, and many turn out to be too optimistic. Here's a more honest breakdown:

Small Site (10-50 pages)

  • Optimistic: 6 weeks
  • Realistic: 8-12 weeks
  • What goes wrong: Content migration takes longer than expected, stakeholder review cycles add 2-3 weeks

Medium Site (50-500 pages)

  • Optimistic: 10 weeks
  • Realistic: 14-20 weeks
  • What goes wrong: Integration complexity gets underestimated, content model needs revision mid-project, design iterations pile up

Enterprise Site (500+ pages)

  • Optimistic: 4 months
  • Realistic: 6-10 months
  • What goes wrong: Everything. Stakeholder alignment, legacy system dependencies, content governance decisions, security reviews, accessibility audits

The number one cause of delays isn't technical. It's decision-making. The migration forces you to make choices about content structure, design systems, and editorial workflows that might have sat unresolved for years. Build in buffer time for those conversations.

How to Budget Without Getting Burned

Here's practical advice for avoiding budget overruns:

  1. Pay for a proper discovery phase. Spend £3,000-£8,000 / $4,000-$10,000 on a 2-3 week discovery before you commit to a full build. This should give you a content audit, technical architecture recommendation, and a much tighter cost estimate.

  2. Budget 20% contingency. Not 10%. Twenty. Content migration surprises are almost guaranteed.

  3. Don't migrate everything. Most Drupal sites have piled up years of content that nobody reads. Use your analytics. If a page hasn't had a visit in 12 months, ask whether it needs to migrate at all.

  4. Consider a phased approach. Migrate the marketing site first, then the blog, then the complex application features. This spreads cost and cuts risk.

  5. Get your editorial team involved early. The costliest change requests come from editors who see the new CMS for the first time at UAT and say "I can't do my job with this."

FAQ

How much does it cost to migrate from Drupal to Next.js in 2026?

For a small site (under 50 pages), expect £12,000-£30,000 / $15,000-$40,000. Medium sites with integrations run £30,000-£75,000 / $40,000-$95,000. Enterprise migrations with complex content models, e-commerce, or multilingual support start at £75,000 / $95,000 and can exceed £200,000 / $250,000. These ranges assume a professional agency engagement in the UK or US.

Is it cheaper to upgrade Drupal or migrate to Next.js?

A Drupal 7 to Drupal 10/11 upgrade often costs 60-80% of what a new Next.js build costs, since it's basically a rebuild anyway. The difference shows up in long-term costs: Next.js hosting is cheaper, developers are easier to find, and you skip the next major Drupal upgrade cycle. For Drupal 9/10 sites that just need a frontend refresh, staying on Drupal is usually cheaper short-term.

How long does a Drupal to Next.js migration take?

Small sites take 8-12 weeks realistically. Medium sites take 14-20 weeks. Enterprise sites take 6-10 months. The biggest variable isn't the code. It's content migration, stakeholder alignment, and integration complexity. Always add 20% buffer to whatever timeline your agency quotes.

Can I use Drupal as a headless CMS with Next.js?

Yes, and it's a valid approach if your team already knows Drupal. Drupal's JSON:API and GraphQL modules work well for headless delivery. The downside: you still need Drupal hosting, security patches, and PHP developers. Many teams use this as an interim step before eventually moving to a purpose-built headless CMS.

What's the best headless CMS to replace Drupal?

It depends on your needs. Sanity works well for developer-heavy teams and custom content models. Contentful suits enterprise teams with structured workflows. Storyblok is strong for visual editing. For simpler sites, even Payload CMS or Strapi (self-hosted, open source) can work. There's no single right answer. It depends on your editorial workflow, budget, and technical preferences.

Should I use Supabase instead of a headless CMS?

Supabase makes sense when your site works more like an application than a content site: think directories, dashboards, user-generated content, or complex relational data. For traditional content publishing (articles, pages, media), a purpose-built headless CMS gives you a better editorial experience out of the box. Some projects use both: a headless CMS for content and Supabase for application data and authentication.

Are UK agency rates cheaper than US rates for Next.js development?

Generally yes, though the gap is usually modest rather than huge. UK senior Next.js developers typically bill £500-£800/day, while US equivalents charge $150-$250/hour ($1,200-$2,000/day). London agencies with enterprise clients often match US pricing, though. The best value often comes from specialist headless agencies rather than large full-service shops, no matter the location.

What are the hidden costs of migrating from Drupal to Next.js?

The most commonly missed costs are: content migration scripting (especially for Paragraphs/Layout Builder content), URL redirect mapping and SEO preservation, media asset migration and CDN setup, editorial training on the new CMS, accessibility testing and fixes, and post-launch performance tuning. Budget at least 20% above your quoted price to cover these.

Key takeaway:

Drupal 7 EOL and a shrinking Drupal developer pool are driving Next.js migrations in 2026.
