NoMethodError undefined method set_inheritance_column for TracMigrate

Added by Sergey Doroshenkov 10 days ago

Hello.

I try to migrate the old redmine database (v. 2.2) to the new windows server and also to upgrade Redmine to the latest version (v. 4.0.1).

I did the following steps:

  1. Istalled Bitnami Redmine Stack on new windows server
  2. Restored the backup of old redmine database to the new MySQL database
  3. And then I try to to execute command "bundle exec rake redmine:migrate_from_trac RAILS_ENV="production"" I get the following error:
C:\Bitnami\redmine-4.0.1-1\apps\redmine\htdocs>bundle exec rake redmine:migrate_from_trac RAILS_ENV="production" 
rake aborted!

That command is used to migrate from Trac to Redmine.
If you are trying to migrate from one version of Redmine to another one you'll have to execute:

bundle exec rake db:migrate RAILS_ENV=production
