MIgrate Redmine 2.2.2 Database to 3.3.0
We have an old version of Redmine, but instead of going through an upgrade process, we're wondering if there's a way we can migrate the DB to the latest version in a fresh Redmine install?
Yes, it's possible.
Install the latest version, point to old database in database.yml and run migration.
make sure to uninstall all plugins on old instance before that.
Will this work from any old version to 3.3? Will it be maintained indefinitely?
