Any gotcha's with upgrading from MariaDB 5.5 to 10.6.5

Just gone through the process of upgrading from Maria v5.5.68 to v10.6.5 and all seems to have gone fine, i.e. Seafile is still running. Any gotcha’s that I might have overlooked?

Basic process:

  1. Backup databases
  2. Stop MariaDB, Seafile and Seahub services
  3. Uninstall old version of MariaDB and cleanup repos
  4. Set-up repo for latest version of MariaDB and install 10.6.5
  5. Start and enable the service again
  6. Update databases using mysql_upgrade -u root -p
