migrating from 1.4 to 2.1.2

Can anybody please tell me how to fix those two errors? (show Issues and Konfiguration)
I get 500 Error with the following lines in production.log

I tried rake migrate:db but it did´nt help.
Maybe I was in the wrong directory?

I tried it in /usr/local/share/redmine-2.1.2 Directory

ActionView::Template::Error (undefined method `field_name'
ActionView::Template::Error (missing attribute: parent_id):

Its my first time installing redmine.
Thanks in advance!

Did you set RAILS_ENV to 'production' before executing migration?

I executed this command:

rake db:migration RAILS_ENV=production

But I´m not sure about the directory
I did in in Redmine Root /usr/local/share/redmine-2.1.2

it was

rake db:migrate RAILS_ENV=production

solved the problem first configure test and develop Enviroment in database.yml
and then restart thin server
