of the hosts to be upgraded and not only on the first one in the list. For this purpose, the test has been moved to the prechecks, and the failures are now shown as a non-fixable problem. Further, specification of the network location of the installer files has moved closer to the upgrade mode selection. Also, moved the hotfix and upgrade related checks immediately after the host liveness check. Signed-off-by: Konstantina Chremmou <konstantina.chremmou@citrix.com>
