Redmine

Greetings

We have a Bitnami Stack Redmine 2.0.2 (Apache/MySQL/Subversion).

I follow the post Updating Redmine code only.

But the command: rake db:migrate RAILS_ENV=production

[root@dionisio htdocs]# rake db:migrate RAILS_ENV=production
==  AddUniqueIndexToIssueRelations: migrating =================================
-- add_index(:issue_relations, [:issue_from_id, :issue_to_id], {:unique=>true})
rake aborted!
An error has occurred, all later migrations canceled:

Index name 'index_issue_relations_on_issue_from_id_and_issue_to_id' on table 'issue_relations' already exists
