You must upgrade the management domain before upgrading workload domains in your environment. In order to upgrade to VMware Cloud Foundation 4.3, the management domain must be at VMware Cloud Foundation 4.1 or higher. If your environment is at a version lower than 4.1, you must upgrade the management domain to 4.1 and then upgrade to 4.3.

Components in the management domain must be upgraded in the following order:
  1. SDDC Manager and VMware Cloud Foundation services. See Upgrade VMware Cloud Foundation Software.
