DxEnterprise software is fully backward compatible and can be updated during normal production without impacting SQL instances or workloads.


To update DxEnterprise software, please follow the procedure below:

  1. Download the latest DxEnterprise software (Client Downloads)
  2. Freeze all nodes to disable InstanceMobility (i.e. right-click on each cluster node and select “freeze node”) - this instructs the cluster not to failover
  3. Uninstall current DxEnterprise software
  4. Install the latest DxEnterprise software
  5. Repeat steps 3 and 4 for all nodes in the cluster
  6. Unfreeze all the nodes to re-enable InstanceMobility
