+Upgrading from one OpenSupports version to another consists in replacing the current files on your server and sometimes run a `.sql` script to upgrade your MySQL database.
+
+## Upgrade v4.0b => v4.1
+
+1. Download the upgrade [zip file](https://github.com/opensupports/opensupports/releases/download/v4.1.0/opensupports_v4.1_update.zip)
+2. Put your system in maintenance (no necessary, but recommended, you can do it in the admin panel).
+3. Replace the OpenSupports files in your server with the content of the zip file.
+4. Execute [this script](https://github.com/opensupports/opensupports/blob/master/db_upgrades/4.1.sql) in your OpenSupports' MySQL database.
+5. Upgrade should be complete. If you had some issues, feel free to open a ticket here at github.
