Abstract: A rollback can be performed after completing an upgrade to components of a virtualized computing environment. When the upgrade is performed, an upgrade bundle having rollback scripts is provided to edges, hosts, and managers in the virtualized computing environment that are to be upgraded. When a rollback is to be performed, the rollback scripts are executed, and the components are rolled back in a reverse order relative to their upgrade order. Data and configuration checking are performed to validate the results of the rollback.

Abstract: The current document is directed to methods and subsystems that validate migration of a virtualized subsystem from a first implementation and/or version to a second implementation and/or version carried out by a semi-automated or automated migration process. Virtualized-subsystem migrations allow a distributed computer system to access new and improved facilities and capabilities provided by a new virtualized-subsystem implementation and/or version. However, there are risks associated with semi-automated and automated migration processes. Independent validation of a migration by the currently disclosed methods and systems ameliorates these risks.

Abstract: Methods and apparatus to generate a shadow setup based on a cloud environment and upgrade the shadow setup to identify upgrade-related errors are disclosed. An example apparatus includes a topology deployment determiner to deploy a shadow setup corresponding to a replica version of a live cloud environment; an upgrade coordinator to upgrade one or more components of the shadow setup; and a reporter to generate a report corresponding to the upgrade.

Abstract: Methods and apparatus to deploy virtual networking in a data center are disclosed. An example apparatus includes: a user interface to receive configuration information for a virtual network system to be installed in a datacenter and store the configuration information in a configuration file; an execution engine to install the virtual network system within the datacenter and to configure the virtual network system based on the configuration file; and a certification engine to validate the deployment and, in response to detecting a deployment failure, presenting, via the user interface, options to response to the failure.
