Drupal-to-Drupal migration ========================== This is a framework based on the Migrate API to ease building migrations from one Drupal site to another. It is only supported at this time on Drupal 7 (i.e., Drupal 7 is the only destination). Besides addressing contemporary needs to migrate to Drupal 7, it is intended to help serve as a proof-of-concept for incorporating the migration approach into core as an upgrade path (http://drupal.org/node/1052692). migrate_d2d =========== The core framework provided here is used by providing your own module, which will register instances of the migrate_d2d classes (or derivations of them). See migrate_d2d_example for one approach, where instances are registered when the Drupal caches are cleared (note that registration updates previously- registered classes with any argument changes).
