Redmine

Each time I've attempted to upgrade my Redmine system, I've run into problems.. Since I've done this on multiple development and one production server so far, the only common denominator is me.

Take note: I am using Bitnami stack for Windows here, but the upgrade scripts are pure Redmine.

At upgrade time, I do the following:

• backup DB
• remove services
• run new Redmine installer (Bitnami)
• copy DB backup, plugins, themes, files to new folder
• start new Redmine instance
• restore DB backup to current DB
• bundle install (environment variables are set up for proxy and rails)
• rake db:migrate
• rake redmine:plugins:migrate

At this point, I inevitably get a message from certain plugins about tables that already exist. Most often this comes from CKEditor plugin regarding the rich_rich_files and rich_rich_images tables.

Am I doing something wrong here? And if not, why is it always such a nightmare to upgrade Redmine..? Any help here would be greatly appreciated. :)
