Enterprise Drupal Reference Architecture
A reference architecture is useful only if it is specific enough to argue with. What follows is a conceptual model for an enterprise Drupal platform, read in the order a request travels, with the decision each layer actu...
Drupal Cutover and Rollback Strategy
The moment a site changes address is the only part of a migration the organization actually experiences. Everything before it is preparation and everything after is stabilization, but the cutover is what gets remembered....

Drupal Site Complexity Assessment
Everything else in an estate migration depends on this. Sequence, effort, test depth, rollback design, staffing and acceptance criteria all follow from knowing which sites are alike, and none of them can be planned hones...
