We have a VCF 3.8 environment that needs to be upgraded. This upgrade has been delayed due to the customer using iSCSI on vSAN and there have been some problems when the iSCSI owner has moved.
Does anyone know the update order of the ESXi hosts (random, by display name, uuid, etc?). Is there anything we can do to limit the upgrade to one or several hosts so upgrades can be staged over multiple change windows?
