The verdict in three sentences
A Drupal site reaching end-of-life is not a comfort you postpone: it is a security deadline that, once passed, exposes the institution to unpatched vulnerabilities. In 2026, two paths open: stay in the ecosystem via a Drupal 10 upgrade, or migrate to a modern headless stack at a higher initial cost but lower 4-year TCO. Budget an order of magnitude of 22,000-50,000 EUR excl. VAT and 12-20 weeks to move 1,200 content items cleanly.
Drupal 10 upgrade vs headless migration
The upgrade stays in the known but carries forward the debt of a heavy CMS; headless migration demands more upfront effort but durably lightens operations.
| Criterion (2026) | Drupal 10 upgrade | Headless migration |
|---|---|---|
| Initial cost excl. VAT | 18,000 - 32,000 EUR | 30,000 - 50,000 EUR |
| Timeline | 10 - 16 weeks | 12 - 20 weeks |
| Skills required | Rare, costly | More available |
| Performance (LCP) | 2.5 - 3.5 s | 0.9 - 1.6 s |
| Hosting cost/year | High | -35 to -45% |
| Maintenance excl. VAT/month | 500 - 900 EUR | 350 - 700 EUR |
| Next migration | In 3-4 years | Evolves without break |
The upgrade reassures short-term but places the institution before the same decision in 3-4 years; headless migration breaks this cycle.
4-year TCO: the gap widens
A public institution reasons over the asset's lifetime. Over 4 years, headless's higher initial cost is absorbed by cheaper operations.
| Line item over 4 years | Drupal 10 upgrade | Headless migration |
|---|---|---|
| Build/upgrade excl. VAT | 25,000 EUR | 40,000 EUR |
| Hosting (4 years) | 9,600 EUR | 5,500 EUR |
| Maintenance (4 years) | 33,600 EUR | 24,000 EUR |
| Specialized skills | 8,000 EUR | 3,000 EUR |
| Next migration | 20,000 EUR (year 4) | 0 EUR |
| Total 4-year TCO excl. VAT | 96,200 EUR | 72,500 EUR |
Over 4 years, headless is about 24% cheaper in total cost: the extra initial investment is more than offset by operations and the absence of a new forced migration.

The real work is content migration: 1,200 pages and news items, a taxonomy to rationalize, and URLs to preserve. The plan includes a content audit (pruning obsolete pages), a taxonomy overhaul, a URL mapping with systematic 301 redirects, and a 2-day editor training. A post-migration control crawl confirms no strategic URL is lost.
Mini case study
Sophie, digital lead of an institution in Amsterdam, runs a Drupal 7 site at end-of-life with 1,200 content items and 800 EUR excl. VAT/month maintenance, for lack of available Drupal skills. The headless migration at 40,000 EUR excl. VAT cuts maintenance to 500 EUR excl. VAT/month and hosting drops 40%. The recurring saving of 3,600 EUR excl. VAT/year, plus no forced migration in 4 years (20,000 EUR avoided), makes the operation more advantageous than a simple upgrade by the third year, while removing the security-cutoff risk.
FAQ
What do we risk staying on an end-of-life Drupal? Unpatched security vulnerabilities, legal risk for a public institution and growing difficulty finding skills. Migration must be planned before the cutoff.
Must we necessarily leave Drupal? No: a Drupal 10 upgrade is valid if the team masters the ecosystem. But it carries forward costly operations and a new migration in 3-4 years.
How do we avoid losing rankings on the 1,200 pages? Through an exhaustive URL mapping, systematic 301 redirects and a control crawl. Executed well, organic traffic holds from go-live.
How long does migration take? Budget 12-20 weeks depending on volume and taxonomy complexity, including a 2-day editor training.
Is headless really cheaper long-term? Over 4 years, about 24% lower TCO thanks to reduced hosting, lower maintenance and no forced new migration.
