6.9.2 -> 7.4.0: db:migrate - Project url can't be blank

Created by: STOIE

Hey guys,

Getting this when trying to go from 6.9.2 -> 7.4.0:

-- add_column(:services, :properties, :text)
   -> 0.0012s
rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:

Validation failed: Project url can't be blank, Token can't be blank/home/git/gitlab/vendor/bundle/ruby/2.1.0/gems/activerecord-4.1.1/lib/active_record/validations.rb:57:in `save!'

Any help? can I manually update something in the DB to overcome this.

Aaron.
