Upgrade from mariadb 10.0 to 10.6

We are planning to upgrade from mariadb 10.0 to 10.6

Needed some clarifications on below;

We will be installing mariadb 10.6 on new machine. Take full db back of 10.0 instance using mariadb-backup (physical backup) tool and restore the same on newly installed 10.6 instance. Once restore is completed, we will run mysql_upgrade. Any challenges with this approach?
