The following procedures provide information about upgrading to VMware Cloud Foundation 4.3 on Dell EMC VxRail.

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. After upgrading to VMware Cloud Foundation 4.3, you can view the versions in your environment and the associated component versions in that release by navigating to Lifecycle Management > Release Versions. Note that the management domain and VI workload domains must be upgraded to the same release version. For example, suppose your environment is at VMware Cloud Foundation 4.2. If you are upgrading to VMware Cloud Foundation 4.3, the management domain and VI workload domains must be upgraded to this release.

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.
