The verdict in three sentences
A site on Drupal 7 has run without official security patches since January 5, 2025, leaving a membership body exposed to publicly documented vulnerabilities. For an association with 1,800 pages and a member directory, there is no "upgrade": it takes a migration, to Drupal 11 or to a headless architecture. The real project risk is not technical but in content migration and the 301 redirect plan, which protect fifteen years of earned traffic.
The four realistic options in 2026
The communications director usually faces four doors. Figures below are 2026 ballpark ranges for the US market on an 1,800-page site with a directory.
| Option | Principle | 2026 ballpark (USD) | Timeline | Main limit |
|---|---|---|---|---|
| Paid extended support (HeroDevs, Tag1) | private patches for Drupal 7 | 8,000 to 20,000 per year | immediate | only buys time |
| Migrate to Drupal 11 | rebuild theme and modules, migrate content | 40,000 to 65,000 | 4 to 6 months | every custom module rewritten |
| Headless (Drupal or SaaS CMS + Next.js) | editorial back office decoupled from front end | 50,000 to 80,000 | 5 to 6 months | two components to maintain |
| Simpler CMS (WordPress) | full rebuild | 30,000 to 50,000 | 4 to 5 months | less granular approval workflow |
| Do nothing | frozen site | 0 now | not applicable | breach and data leak risk |
Extended support only makes sense as a 6 to 12 month bridge during migration. For an organization holding member data, staying exposed also creates liability under New York's SHIELD Act if a breach occurs.
What actually drives the budget
The chosen technology matters less than content volume and condition. Here is a typical breakdown for a Drupal 11 migration.
| Workstream | Detail | Share of budget | Ballpark (USD) |
|---|---|---|---|
| Discovery and inventory | audit of 1,800 pages, content types and modules | 8% | 3,200 to 5,200 |
| Design and theme | WCAG 2.1 AA templates, components | 20% | 8,000 to 13,000 |
| Development | content types, member directory, search, forms | 30% | 12,000 to 19,500 |
| Content migration | migration scripts, cleanup, media | 20% | 8,000 to 13,000 |
| 301 redirect plan | mapping table, tests, Search Console monitoring | 7% | 2,800 to 4,550 |
| QA, training, launch | testing, editor training | 15% | 6,000 to 9,750 |
A tip that saves money: use the inventory to remove 30 to 40% of pages (stale news, duplicates, pages with no visits in two years). Migrating 1,100 pages instead of 1,800 cuts the migration line and clarifies navigation. Removed pages get a 301 to the closest page, never to the homepage.
The member directory deserves separate handling: it is often the most visited and most externally linked section. Profile URLs must be kept or redirected one by one.
The 4 to 6 month timeline
- Month 1: inventory, option choice, requirements, extended support if needed.
- Months 2 and 3: design, theme and content type development, first migration scripts.
- Month 4: dry-run migration, editor acceptance testing, redirect preparation.
- Month 5: final migration, launch, 404 monitoring for 8 weeks.
- Month 6 (headless or deep accessibility work): WCAG audit, fixes, accessibility statement.

Rachel, communications director of a professional association in New York, compares two three-year scenarios. Scenario A: extended support at 14,000 USD a year for three years, migration postponed, so 42,000 USD with no improvement. Scenario B: six months of extended support (7,000 USD) and a Drupal 11 migration at 55,000 USD, so 62,000 USD.
Scenario B costs 20,000 USD more, but delivers an accessible site maintained through at least 2028 and faster publishing. The four-person editorial team drops from 25 to 15 minutes per news item; at 400 posts a year, that frees about 67 hours annually. Above all, scenario A still leaves the full migration to pay in 2028, likely at a higher price.
FAQ
Is it dangerous to stay on Drupal 7 in 2026?
Yes. Any vulnerability found since January 2025 stays open without private support, and attack bots target known versions. A public site with forms and a directory is a frequent target.
Can we migrate straight from Drupal 7 to Drupal 11?
Yes, with the Migrate module, without going through versions 8 to 10. Custom modules and the theme still need rewriting, often 50% of the budget.
How many 301 redirects should we plan?
One per indexed or externally linked URL, often 1,500 to 2,500 rows for an 1,800-page site. Monitor 404 errors for at least 8 weeks after launch.
Is headless worth the premium?
It pays off if you publish to several channels (site, app, kiosks) or need a very fast site. For a standard membership site, the 10,000 to 15,000 USD gap is not always recovered.
What does Kolonell charge for this kind of migration?
Institutional sites are always quoted on request, after a content and module inventory. The estimate reflects the real number of pages to migrate and accessibility requirements.
