body: <p>I'm planning to upgrade MariaDB Galera cluster from 10.1 to 10.2. Does anyone have details for steps to upgrade? My idea is something</p>
  
  <ol>
  <li>Backup</li>
  <li>Shutdown cluster</li>
  <li>Uninstall 10.1 from each node</li>
  <li>Install 10.2 to each node</li>
  <li>Run mysql_upgrade at node which going to started first</li>
  <li>Configure the first node and start </li>
