Upgrading Your Cluster

A cluster can be upgraded form the current version to one new minor version for example from version 1.20 to 1.21 Once the upgrade procedure starts, the system will replace all old version nodes with new ones.

Notes

  • Only High Available clusters can be upgraded
  • Upgrade is performed on one node at a time until all nodes are upgraded, this may take some time depending on the cluster size
