Heya Alexander,

Welcome back to the forums!

Upgrading Mattermost to the latest version and migrating the MySQL database is indeed a feasible method. Here are the general steps you can follow:

  1. Set up a new server: Install Ubuntu 22.04 on the new server and ensure it meets the hardware requirements for Mattermost. You can refer to the Ubuntu documentation for installation instructions.
  2. Install and configure MySQL: Install MySQL Server 8.0.34 on the new server and configure it according to your needs. You can refer to the MySQL documentation for installation and configuration instructions.
  3. Install the latest version of Mattermost: Follow the Mattermost installation guide for Ubuntu (Redirect) to install the latest version on the new server. Make sure to follow the instructions specific to Ubuntu 22.04.
  4. Migrate the MySQL database: Once you have the latest version of Mattermost installed, you can migrate the MySQL database from the old server to the new server. You can use the mysqldump command on the old server to export the database, then import it on the new server using the mysql command. Here is an example of how to export and import the database:On the old server:
mysqldump -u <username> -p <databasename> > mattermost.sql

On the new server:

mysql -u <username> -p <databasename> < mattermost.sql

Make sure to replace <username>, <databasename>, and mattermost.sql with appropriate values.
5. Verify the migration and upgrade: Start the Mattermost server on the new server and ensure everything is working correctly. Verify that all users, channels, and messages are available in the new version. Test the functionality to ensure a successful migration.

Regarding your question about deploying Mattermost with Omnibus, it is a recommended method for simplifying setup and maintenance, especially if you’re running the server and database on a single system. However, it’s not mandatory, and you can choose the method that suits your requirements and infrastructure.

If you encounter any issues during the process, feel free to ask for further assistance!
