Hello,

I'm trying to update my redmine 1.x (sqlite) to 3.x (mysql)

bundle exec rake db:migrate RAILS_ENV=production gives me this error (full stack attached)

ActiveRecord::IrreversibleMigration: 

Can't decypher salted passwords. This migration can not be rollback'ed.

I don't know how to solve it, any suggestions?
