Redmine

Hi!

I've had a bitnami redmine 1.0.2 stack running for about a year. It came with...

ruby 1.8.7
rails 2.3.9
rack 1.0.1

Now I want to bring redmine up to date, to version 1.3.1.

http://www.redmine.org/projects/redmine/wiki/RedmineInstall tells me 1.3.x requires...

ruby 1.8.7
rails 2.3.14
rack 1.1.x

So I can't just replace the application files, I'd also need to update rails and rack. So it's probably in my interest to use a fresh bitnami redmine 1.3.1 stack because it will come with all the necessary dependencies, none of which I have any experience using and/or keeping up to date (which was the point of using a bitnami stack in the first place).

But if I just back up the database / conf files / uploaded files, uninstall the 1.0.2 stack, and install the 1.3.0 stack, the database schema will be different, so I won't likely be able to just use the old database.

How do I do this? I'm a web developer in other languages so I'm familiar with the concepts, I just have no experience with ruby/rails/rake/rack/etc. Any help would be very much appreciated.

Thanks
