Cannot migrate database when upgrading from7.0 to 7.2

Created by: keith9820

When I run the migrate task I get this error:

# sudo -u git -H bundle exec rake --trace db:migrate RAILS_ENV=production
[deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message.
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:migrate
