Abstract: The disclosure provides for analyzing upgrade and migration readiness. Embodiments include receiving an indication to upgrade a software product and a selected upgrade path identifying a target-upgrade version. Embodiments include accessing an array of pre-upgrade procedures comprising code for identifying one or more conditions that must be met before the software product can be upgraded based on the accessed array being associated with the software product. Embodiments include executing one or more of the pre-upgrade procedures in advance of upgrading the software product. Embodiments include accessing one or more autonomous remediation scripts from the repository based on identification of one or more failed pre-upgrade procedures. Embodiments include executing the one or more autonomous remediation scripts to cure the one or more failed pre-upgrade procedures and initiating an upgrade of the software product based on identifying that the array of pre-upgrade procedures successfully completed execution.

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: Example methods are provided for a network scanning controller to perform agent-based network scanning in a software-defined networking (SDN) environment. In one example, the method may comprise identifying multiple networks for which network scanning is required, performing a first network scan using a first agent to obtain first address mapping information associated with multiple first workloads, and performing a second network scan using a second agent to obtain second address mapping information associated with multiple second workloads. The first agent and the multiple first workloads may be located in a first network, and the second agent and the multiple second workloads in a second network. The method may also comprise generating aggregated address information based on the first address mapping information and the second address mapping information.

Abstract: Example methods and systems to perform distributed upgrade of a component of a data plane are disclosed. One method may include collecting information associated with all the components, preparing a upgrade plan by associating a first set of tasks of the upgrade plan with a first manager and a second set of tasks of the upgrade plan with a second manager based on the collected information, and distributing the first set of tasks to a first upgrade coordinator of the first manager and the second set of tasks to a second upgrade coordinator of the second manager.

Abstract: Example methods and systems to perform a distributed backup operation or a distributed restoration operation in a virtualized computing environment including a plurality of components and a plurality of policies are disclosed. One method may include identifying a component or a policy of the plurality of components or policies in response to receiving a first task associated with the distributed backup operation or the distributed restoration operation. In response to the first task associated with the distributed backup operation, the method include generating a backup file having a configuration of the component, but not any configuration of other components of the plurality of components, or a configuration of the policy, but not any configuration of other policies of the plurality of policies; and storing the backup file on a remote server.
