Upgrading 1.1 to 1.2 with RPMS (yum) (resolved)

If you run into trouble after running an yum update and getting the latest
Foreman Packages:

do :

cd ~foreman
/usr/bin/ruby193-rake db:migrate RAILS_ENV="production"

yum install ruby193-rubygem-passenger-native-4.0.5-3.el6.x86_64

This fixed for me as I was having:

no such file to load – bundler_ext (LoadError)

Also you may need to comment the lines generating error on your httpd/conf.d/
#RailsAutoDetect On
And add:
PassengerRuby /usr/bin/ruby193-ruby
