MariaDB 10.6 - Upgrade to 11.x

I’d like to update my database version to the most restent mariadb:
My System: Ubuntu 22.04 server
At the moment:

stefan@mautic01:~$ mariadb --version
mariadb  Ver 15.1 Distrib 10.6.16-MariaDB, for debian-linux-gnu (x86_64) using  EditLine wrapper

As i installed the server, i used for apache and mariadb that command:
apt install -y apache2 && apt install -y mariadb-server && apt install -y mariadb-client

Would anyone support me here? I have a database backup and a complete server image backup - so i’m save. But the tutorial to upgrade i saw here has many things, i’m not sure… Upgrading from MariaDB 10.11 to MariaDB 11.0 - MariaDB Knowledge Base

I know now, that 10.6.16-MariaDB is the default database for my Ubuntu 22.04
So i let that. Thought i need to update the database, but now i’ll let it go now.
