cartodb/UPGRADE

3.0.0 -> 3.1.0
--------------
* Run rake task:
    bundle exec rake cartodb:overlays:create_overlays

    if the task is run more than one time (because something happened) a flag to remove previous overlays should be pass

    bundle exec rake cartodb:overlays:create_overlays[true]

    this will remove all the overlays for visualizations so it MUST NOT be called after visualization overlays has been customized

2.x -> 3.0.0
------------
* Install CartoDB extension version 0.3.x
* Run rake tasks:
  - bundle exec rake cartodb:db:create_default_vis_permissions
  - bundle exec rake cartodb:db:populate_permission_entity_id


General notes
-------------

 - Redis server must be listening on the configured

   steps below to work
