The verdict in three sentences
Since Drupal 7 reached end of life in January 2025, a trade association site still running it receives no official security patches, and every month of delay raises both risk and exit cost. In 2026 three options dominate: Drupal 10/11 (EUR 25,000 to 55,000 excl. VAT in Paris), WordPress (EUR 15,000 to 30,000) or a headless Next.js + CMS architecture (EUR 30,000 to 60,000), over 3 to 6 months, while American associations in New York typically budget USD 40,000 to 120,000 for the same move. The right choice depends less on technology than on the volume of content to migrate (2,000 to 8,000 items), the members area and the skills of the team that will publish afterwards.
Comparing the three migration options
A typical association publishes news, legal or policy briefs, a member directory, an events calendar and a members-only area. These functions determine the best option.
| Criterion | Drupal 10/11 | WordPress | Headless Next.js + CMS |
|---|---|---|---|
| 2026 budget excl. VAT (Paris) | EUR 25,000-55,000 | EUR 15,000-30,000 | EUR 30,000-60,000 |
| Timeline | 4-6 months | 3-4 months | 4-6 months |
| Complex members area (rights by membership class) | Very well suited | Possible via plugins | Suited, custom-built |
| Migrating Drupal content and taxonomies | Native migration tools | Dedicated scripts | Dedicated scripts |
| Ease of publishing for staff | Good after training | Very good | Good, depending on CMS |
| Performance and security | Good | Depends on plugins | Excellent |
| Monthly maintenance contract | EUR 600-900 | EUR 400-650 | EUR 500-850 |
Drupal 10/11 remains the logical choice if the members area manages fine-grained rights (by membership class, region, committee). WordPress suits associations whose site is mainly editorial. Headless makes sense when performance, multichannel delivery or a strong visual identity come first.
The underestimated line item: content migration
The technical migration is rarely what overruns. Migrating, cleaning and redirecting content is what weighs, especially for an association that has accumulated briefs and circulars over 10 or 15 years.
| Content volume | Migration effort | Indicative 2026 cost excl. VAT | 301 redirects |
|---|---|---|---|
| 2,000 items | Automated migration, sample checks | EUR 3,000-6,000 | 2,000-2,500 URLs |
| 4,000 items | Automation and field clean-up | EUR 6,000-10,000 | 4,000-5,000 URLs |
| 6,000 items | Editorial triage, partial archiving | EUR 9,000-14,000 | 6,000-7,000 URLs |
| 8,000 items and more | Prior audit, archiving plan | EUR 12,000-18,000 | 8,000 URLs and more |
| Attachments (PDFs, circulars) | Renaming and re-indexing | EUR 1,500-4,000 | Depending on volume |
| Member accounts | Credential migration, password reset | EUR 1,000-3,000 | Not applicable |
A prior audit often allows 30 to 40 % of obsolete content to be archived, cutting the bill accordingly and improving search rankings.
Realistic timeline
An association migration usually follows five steps: content audit and mapping (3 to 4 weeks), target choice and design (4 to 6 weeks), development and migration scripts (6 to 10 weeks), acceptance testing with staff and a few members (2 to 4 weeks), then switchover with a redirect plan and 30 days of Search Console monitoring. Scheduling the switchover away from the annual general meeting avoids friction.

Isabelle, executive director of an association of 1,200 member companies, runs a Drupal 7 site with 5,000 items and a members area organised by membership class. She picks Drupal 11 for EUR 42,000 excl. VAT, including EUR 11,000 of content migration, with maintenance at EUR 750 per month. The audit archives 1,800 obsolete items, saving about EUR 4,000 in migration work. Before the project, a vendor charged EUR 1,100 per month of extended support to keep Drupal 7 alive, with no guarantee. Over three years, the new site's total cost reaches EUR 69,000, against EUR 39,600 of extended support over the same period for a site that keeps ageing and stays exposed. A comparable New York association would budget USD 40,000 to 120,000 for the build alone.
FAQ
Is Drupal 7 still safe in 2026?
No, it has had no official patches since January 2025. Paid extended support exists, around EUR 800 to 1,200 per month, but it only delays the migration.
Which option is cheapest?
WordPress, at EUR 15,000 to 30,000 excl. VAT and 3 to 4 months. It fits if the members area stays simple.
Can search rankings be kept during migration?
Yes, with a complete 301 redirect plan, often 2,000 to 8,000 URLs for an association. A temporary 5 to 15 % traffic dip for 4 to 8 weeks is common.
What does maintenance cost after migration?
Budget EUR 400 to 900 per month depending on technology and change volume. Drupal sits at the top of the range.
Should all content be migrated?
Rarely. An audit lets you archive 30 to 40 % of obsolete content and cut migration cost accordingly.
