Redmine

Hi, I have an issue with DB when upgrading redmine from 1.4 to redmine-2.2.4, running the following command :

sudo RAILS_ENV=production rake db:migrate 

I get the following error regarding comments table :

** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:migrate
==  CreateComments: migrating =================================================
-- create_table(:comments)
rake aborted!
An error has occurred, all later migrations canceled:
