Hello everyone, I used to work on a project about migrating our system from trac to redmine.

This summer at my first attempt I was able to migrate some parts of our bug tracking database.

But, know I see that there is a new stable releases, I want to migrate completely this time.

Is there anyone who accomplished migration completely?

*at the attachment you can see my migrate_from_trac.rake file, which is edited due to:
-self.inheritance_column = :none instead of set_inheritance_column :none
-self.primary_key = 'name' instead of #set_primary_key :name
-correcting the rake file according to *timestamps patch

Using that script only worked when I spun up an Ubuntu 14.04 virtual and did the migration there.
