Drupal 7 to Drupal 11 Migration Cost in Germany: What to Expect in 2026

If your organization in Germany is still running Drupal 7, you already know the headline: Drupal 7 reached end of life on January 5, 2025. Every new vulnerability since that date is permanently open on your site. No patch is coming.

What most organizations don't know is what a migration to Drupal 11 actually costs — not the “costs vary depending on complexity” answer every agency gives, but real numbers tied to real variables. This guide covers both: what the numbers are, and what actually moves them up or down.

Why Germany Is a Specific Case

Germany has one of the highest concentrations of Drupal 7 sites in Europe — particularly in government, education, healthcare, and mid-size enterprise. German organizations tend to run stable, long-lived platforms, which is exactly why so many are still on Drupal 7 five years after the first end-of-life discussions started.

The German market also has specific considerations that affect migration cost:

• GDPR compliance requirements mean data handling during migration needs careful documentation

• German-language multilingual setups often require extra content migration work

• Many German Drupal 7 sites use contrib modules that were popular in the German community but have no maintained Drupal 11 equivalent

• German agencies typically bill €60–€140 per hour for senior Drupal developers — higher than Eastern Europe, lower than US agencies

Drupal 7 to Drupal 11 Migration Cost Ranges in 2026

Based on current market data from agencies working in the European market, here is what a Drupal 7 to Drupal 11 migration typically costs:

For simpler German sites without heavy custom development, Interdruper — a European Drupal agency — lists migration costs starting from €3,000 for basic sites. That lower end reflects small, mostly standard sites with limited content and no custom modules. Most German organizational sites will land in the mid-range or above.

What Actually Drives the Cost Up

The most common mistake organizations make is assuming the migration cost is mainly about moving content. It isn't. Content migration is straightforward and well-tooled. What's not straightforward is everything around it.

Contributed Modules With No Drupal 11 Equivalent

Drupal 7 has thousands of contrib modules. Many of them — particularly older ones popular in the German community — have no maintained Drupal 11 version. Each one that needs to be rebuilt or replaced adds development time. A site with five or six of these can add €15,000–€40,000 to the project.

Custom Themes

Drupal 7 themes use PHPTemplate. Drupal 11 uses Twig. These are fundamentally different templating systems, which means your existing theme cannot be reused. A full theme rebuild in 2026 costs €7,000–€25,000 depending on complexity. If your site has a heavily custom frontend, expect the higher end.

Third-Party Integrations

CRM connections, payment systems, ERP integrations, LDAP authentication — each one needs to be retested and often rebuilt against Drupal 11's API layer. German organizations in particular tend to have legacy ERP integrations (SAP, Dynamics) that require careful handling. Budget €3,000–€15,000 per integration.

GDPR and Data Handling Documentation

German and EU data protection requirements mean that migration projects need documented data handling procedures for the migration process itself. This adds project management and legal review time that organizations in other regions don't always budget for.

German-Language Content and Multilingual Setup

If your Drupal 7 site serves content in multiple languages — German plus English, or German plus regional variants — the multilingual content migration adds complexity and testing time. Drupal 11's multilingual architecture is significantly different from Drupal 7's, which means this isn't a simple lift-and-shift.

Why a Migration Beats a Rebuild for Most German Sites

Some agencies will suggest scrapping your Drupal 7 site and rebuilding from scratch. For a small number of sites, that's actually the right answer. For most German organizational sites — particularly those with substantial content libraries, established user workflows, or deep integrations — migration is the faster and cheaper path.

A migration preserves your content structure, your URL architecture, and your SEO equity. A rebuild starts from zero on all three. If your site has been accumulating domain authority and organic traffic for years, that's not something you want to throw away.

The December 2026 Deadline and What It Means for Cost

Drupal 10 reaches end of life on December 9, 2026. After that date, no more security patches for Drupal 10 core or contributed modules. For organizations still on Drupal 7, the situation is already past that point — Drupal 7 lost community support on January 5, 2025.

What December 2026 means practically for German organizations is this: every organization running Drupal 10 has the same deadline. The available pool of experienced Drupal developers in Germany and Europe is finite. Q4 2026 will be the most expensive and least available time to start a migration.

Organizations that start their migration in July or August 2026 will finish before the deadline, work with teams that are available and not under deadline pressure, and pay standard market rates. Organizations that start in October will pay a premium — and take on the risk of a rushed project.

How to Get a Reliable Quote in Germany

The single most important thing you can do before getting a quote is run the Upgrade Status module on your existing site. This free Drupal contrib module scans your installation and reports which contributed and custom modules are compatible with Drupal 11 and which aren't. The output of this audit is the most important input to any accurate quote.

Without this audit, any quote is a guess. With it, a good agency can give you a number that will hold.

• Install Upgrade Status via Composer: composer require drupal/upgrade_status

• Run it against your production database

• Share the output with any agency you're evaluating

• Use it to compare quotes — if two agencies give very different numbers for the same scope, ask why

Frequently Asked Questions

Can I migrate directly from Drupal 7 to Drupal 11?

Yes. Drupal provides migration tooling specifically for Drupal 7 to Drupal 11. There is no requirement to pass through intermediate versions. The Migrate API handles the core content migration, and your development team will handle module compatibility and theme rebuilding separately.

How long does a Drupal 7 to Drupal 11 migration take in Germany?

For a small site with limited custom development: 4 to 8 weeks. For a mid-size German organizational site: 8 to 14 weeks. For a complex enterprise platform with custom modules and multiple integrations: 3 to 6 months. These timelines assume the Upgrade Status audit has been completed before work begins.

Should we migrate to Drupal 11 or wait for Drupal 12?

Migrate to Drupal 11. Drupal 12 is scheduled to ship the week of December 7, 2026. Putting a production site onto a newly-released major version immediately is not a safe strategy. Drupal 11 is stable, its contributed-module ecosystem is mature, and it will be supported until approximately 2028. The migration you do in 2026 to Drupal 11 is the right move for the next two years.

What happens if we stay on Drupal 7 past January 2025?

Drupal 7 reached community end of life on January 5, 2025. After that date, no security patches are issued for Drupal 7 core or contributed modules by the Drupal community. Any vulnerability discovered after that date remains permanently open on an unpatched site. Paid extended support is available through some vendors, but it covers core only — not the contributed modules your site likely depends on.

Common Questions — Answered Directly

How much does a Drupal 7 to Drupal 11 migration cost in Germany?

Between €12,000 and €220,000. Small sites with standard content and no custom modules: €12,000–€35,000. Mid-size sites with integrations and some custom development: €35,000–€80,000. Large enterprise platforms: €80,000–€220,000 and above. German agencies typically bill €60–€140 per hour for senior Drupal developers.

How long does a Drupal migration take in Germany?

4 to 8 weeks for small sites. 8 to 14 weeks for mid-size organizational sites. 3 to 6 months for complex enterprise platforms. These are working timelines assuming the pre-migration audit is done before development starts.

What is Drupal 7 end of life in Germany?

Drupal 7 reached end of life globally on January 5, 2025. This applies equally to German organizations. After that date, no security patches are issued by the Drupal community. German Drupal 7 sites running today are operating without security coverage.

Is it better to migrate to Drupal 11 or wait for Drupal 12?

Migrate to Drupal 11 now. Drupal 12 ships the week of December 7, 2026. Running production infrastructure on a just-released major version is not standard practice. Drupal 11 is stable, fully supported, and the right migration target for 2026. The window to migrate without Q4 deadline pressure closes in August.

What does a Drupal migration include?

A full Drupal 7 to Drupal 11 migration includes: pre-migration audit (Upgrade Status), content type and field mapping, module compatibility resolution (rebuild or replace unsupported modules), theme rebuild in Twig, content migration using the Migrate API, URL redirect mapping, integration retesting, accessibility and performance QA, and post-launch support.
