How to upgrade Redmine version?

​To upgrade Redmine, first back up your database and files to safeguard your data. Ensure your server meets the new version's requirements, including compatible Ruby and Rails versions. Download the latest Redmine release, transfer essential configuration files, and install necessary dependencies. Finally, migrate the database, verify plugin compatibility, and restart your server to complete the upgrade. 

If you want to upgrade Easy Redmine, you can choose between two methods:​

A) Docker compose: This streamlined approach uses Docker to replace old containers with new ones via a single command. ​

B) Manual (Legacy) update: This method involves several steps, including backing up your application, downloading the latest package, preserving configurations, and restarting your server. ​

While the manual method offers more control, it's more prone to errors compared to the Docker approach.
