You can schedule the remediation process of hosts, virtual machines, and virtual appliances by using the Remediate wizard.
You can schedule remediation for all hosts or all virtual machines in a container object from the vSphere inventory. You can perform scheduled orchestrated upgrades of the hosts or virtual machines in a selected container object.
To schedule remediation, you must specify a time for the remediation process on the Schedule page of the Remediate wizard.
You cannot edit existing scheduled remediation tasks. You can remove a scheduled remediation task and create a new one in its place.
If your vCenter Server system is part of a connected group in vCenter Linked Mode, and you have installed and registered more than one Update Manager instance, you can create scheduled tasks for each Update Manager instance. Scheduled tasks you create are specific only to the Update Manager instance you specify and are not propagated to the other instances in the group. From the navigation bar, you can specify an Update Manager instance by selecting the name of the vCenter Server system with which the Update Manager instance is registered.
