Necessary steps before the upgrade
Before starting the upgrade, make sure that you have an up-to-date and properly finished backup of the MyQ database. The database can be backed up either manually in MyQ Central Easy Config or automatically as a scheduled task in the MyQ web administrator interface. To make sure that the backup file is preserved, it is recommended to copy the database backup file to a different location.
Upgrading MyQ (all nodes)
The upgrade needs to be performed on each node of the cluster. To be able to upgrade MyQ on a node, you need to have access to the shared cluster disk, so the node has to be active. Therefore, you need to switch the active mode between all of the nodes (move the MyQ server role between the nodes).
Before upgrading MyQ on the nodes, take all the MS Cluster resources, except for Storage and Server Name, offline.
To upgrade MyQ on all nodes, start with the currently active node (the owner of the MyQ server role) and do the following:
Start All services via MyQ Central Easy Config.
Run the MyQ installation file.
Finish the installation process.
Stop All services via MyQ Central Easy Config, and then close the MyQ Central Easy Config application.
Move the MyQ server role to the next node and repeat all the steps.
After MyQ is upgraded on all the nodes, bring all the MS Cluster resources online.
During the installation, you might encounter a warning message about a problem related to updating the MyQ database. In such cases, continue with the setup, as the problem does not impact the installation.
