Bilingual Platform Upgrade

Upgrade aging Drupal 7 platform to Drupal 10 with strict requirements on data preservation, minimal disruption, and language support

The Approach

Understanding Risk and Priorities

We mapped critical systems: user accounts, bilingual content, IQ test flow, and event registrations. The membership database required full integrity during migration.

Automation-First Migration Plan

We created AI-driven scripts to handle data conversion, language mapping, and structural shifts to Drupal 10. Custom scripts were tailored for Mensa's bilingual content and event modules.

Rebuild without Breaking UI or Workflows

Themes were converted to Twig. Components were ported to maintain pixel-perfect layouts in both languages. Payment and registration flows were preserved.

Migration Execution in Controlled Phases

We first ran trial upgrades, fixing edge cases with automated diffs and visual comparison. Then followed the full migration with staged deployment and rollbacks ready.

Full Validation: Data, UX, Language

Post-upgrade, we ran automated screenshot comparison tools, checked member flows manually, and validated bilingual content placement. Final review included live tests of payment and registration.

Bilingual Platform Preservation

All site features carried over. Zero user downtime. No regressions. All content remained intact, and bilingual UI consistency was maintained. Future upgrades now require less effort due to platform modernization.
