Three months after Drupal 8.0.0 comes out, security support for Drupal 6 ends. That means before we release 8.0.0, we need to ensure that it's possible for the 130,000+ sites still running Drupal 6 to move to a newer version.
We need one or both of the following:
- A working upgrade path with no data loss from Drupal 6 to Drupal 7. (No critical "D7 upgrade path" issues).
- A working Drupal 6 => Drupal 8 migration path (already in core) that's exposed through a UI available to site builders.
As of June 1 2015, the following are the outstanding issues blocking this meta from closing:
D6 to D7
D6 to D8
