Now that Drupal 8.0.0 is released, let's take a look at all the components of the Drupal migration ecosystem and where they stand now. To provide context to those familiar with migration under Drupal 7, I will show where the pieces came from. First, general migration support:
Feature | D7 | D8 | D8 status |
Basic migration framework | migrate (contrib) | migrate (core), plus destination plugins in core modules | Experimental |
General-purpose drush commands | migrate (contrib) | migrate_tools (contrib) | The most common commands (ms, mi, mr, etc.) are working |
