I'm trying to upgrade a Drupal 6 site to Drupal 7. I do:
cd /path/to/sites/drupal6-site drush sup
However I get the errors:
Command site-upgrade needs a higher bootstrap level to run - you will need to invoke drush from a more functional Drupal environment to run this command.
Command site-upgrade needs the following modules installed/enabled to run: update.
The settings file is at
drush dl update (a module I'm apparently missing) also reports:
No release history was found for the requested project (update).
What do I have to do to get
drush to bootstrap?
