The following procedures provide information about upgrading to VMware Cloud Foundation 4.3.1 or VMware Cloud Foundation 4.3.

You can perform a sequential or skip level upgrade toVMware Cloud Foundation 4.3.1 from VMware Cloud Foundation 4.3, 4.2.1, 4.2, 4.1.0.1, or 4.1.

You can perform a sequential or skip level upgrade toVMware Cloud Foundation 4.3 from VMware Cloud Foundation 4.2.1, 4.2, 4.1.0.1, or 4.1. If your environment is at a version earlier than 4.1, you must upgrade the management domain and all VI workload domains to VMware Cloud Foundation 4.1 and then upgrade to VMware Cloud Foundation 4.3.

Your environment may contain workload domains at different VMware Cloud Foundation releases. You can view the versions in your environment by navigating to Lifecycle Management > Release Versions.

When you upgrade your environment to a later release, you can choose different target releases for workload domains. However, the management domain and VI workload domains must be upgraded to the same release version. For example, suppose your environment includes VI workload domains at 4.2 and 4.2.1. If you upgrade the management domain to VMware Cloud Foundation 4.3, all VI workload domains must be upgraded to this release as well.

Upgrades are applied on a workload domain basis. The management domain contains the core infrastructure, so you must upgrade the management domain before upgrading the other VI workload domains. You must upgrade all required components to keep your system in an optimum state.
