Hi Bryan, 10.5 has only a year of maintenance to go - https://mariadb.org/about/#maintenance-policy With your infrequent updates wouldn't 10.11 be a better fit? The crash safety during table alterations of 10.6 at least is a good feature to have.
On the mechanism itself, sounds like a good plan to me. You should always do the --prepare from the version you backed up with, in this case Percona Xtrabackup. After this is done the datadir can be used directly by MariaDB 10.5. No MariaDB-backup intervention is needed. You may want to use MariaDB-backup to create the replicas from the promoted 10.5 primary. On Fri, 7 Jun 2024 at 04:29, Bryan K.
