Plugin to merge two Redmine databases.
Follow the Redmine plugin installation steps at: www.redmine.org/wiki/redmine/Plugins
Restart your Redmine web servers (e.g. mongrel, thin, mod_rails)
Run the merge as described below
Make sure you backup both of your databases. There is no undo for these commands.
Edit the config/database.yml in the Redmine root, adding a definition for the source_redmine:
production: adapter: mysql host: localhost username: root password: password database: redmine_target source_redmine: adapter: mysql host: localhost username: root password: password database: redmine_import
Run the included rake task from the Redmine root “rake redmine:merge_redmine RAILS_ENV=production”
When it's completed, the contents of the source_redmine database (redmine_import above) should have been merged into your production database (redmine_target).
Before running the rake task, run “rake redmine:data_report RAILS_ENV=production” to print out the total number of records you are using in your target database. After the migration, you can rerun this to see how many were added.
