Redmine

I am trying to migrate a postgres database from redmine 0.7.1 to 0.8.4 using jruby. Here is the error I am seeing.

** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:migrate

I looked in the 0.7.1 db/migrate directory and 092_change_changes_from_revision_to_string.rb is the last one listed. I am going to continue to poke around but any suggestions on a workaround?

Thanks
