Date, time, and environmental variables may vary depending on your environment.
The client & server clusters participating in the HCI Mesh are on different ESXi versions resulting in the DFC pre-check failing with "Detected host(s) are running in mixed mode, please upgrade ESX servers to the same version."HCI Mesh checks the server cluster's compatibility with the client cluster as part of the DFC pre-check.
Ensure all vSAN clusters participating in the HCI Mesh are on the same ESXi version.
