Redmine

Hello,
I have two redmine versions running. The first is the Redmine 1.0.4; the second version is Bitnami Redmine 2.5.

I want to move all my database information to the Bitnami Redmine database.

I followed this guide:
http://bitnami.com/forums/forums/redmine/topics/fresh-install-of-rs-redmine-how-to-bring-old-db-across

But I came along with several problems regarding rake:migrate command.
I edit manually the client.rb file, and adding username and password for the database.

When I finally manage to run the rake:migrate command (also tried with bundle exec rake:migrate), and tried to go into redmine, I got a "No server found".

Any Idea what could I be doing wrong?
