Approach
Cutover is an origin switch inside Cloudflare: www.padi.com stops pointing at the legacy origin and starts pointing at the new frontend. No DNS change is involved, so the switch takes effect in seconds and rollback is the same switch in reverse. An intermediate hostname such as beta.padi.com can be used for a soft launch.
Retiring the legacy estate
| Legacy component | Retire when |
|---|---|
| Legacy Drupal 10 site on Acquia | Traffic and redirects verified on the new platform |
| Apex padi.com redirect, served by the legacy Acquia application | Apex redirect moved to Cloudflare |
| WordPress blog and Pros blog (divejobs is out of scope) | Migrated content and redirects verified |
| Vue account app (account.padi.com) | Owned by PADI; a Next.js rebuild exists, ownership to be decided (Q-15) |
| Other country domains on the legacy Drupal (padi.com.cn, dive.padi.co.jp) | Out of scope; they stay on the legacy platform for now |
