Hi, We have a three node MariaDB Galera cluster on version 10.1.14 an we would like to upgrade to 10.1.18. Our approach to this was to offline a node upgrade it and then add it back to the cluster and allow it to do an IST to catch up (rinse and repeat for other two nodes).
However this would mean that we will have a period of time where nodes in the cluster will be on different minor versions, is this safe, or will it possibly cause some kind of data corruption or crash?
