Upgrade path/manual(s) from older LTS-version to newer LTS

    Description

      We have many MariaDB 10.5.x Galera clusters on production, up to +10TB dataset sizes.
      10.5 reaches EOL 24 Jun 2025 which is not that far away (1.5y ahead atm)

      What is needed:

      • Upgrade path from 10.5 to 10.11
      • Studying what is needed to be able to successfully upgrade live prod system
      • Manuals including cases for standalone, master-replica and Galera cluster setups

      It is also important to reduce outage-window(s) to as short as possible.
      Thank you
