Start an MSM VM upgradeExecute the MSM VM upgrade file on the MSM VM. Update the MSM credential manager service If the root or VxBlock Central user password has been changed on the Core VM, update the MSM credential manager service with the new password. Verify the MSM VM upgrade After completing the upgrade process, use the VxBlock Central dashboard to verify that the version number of the MSM corresponds to the version that you installed.
