It's an appliance supplied by the vendor therefore you should not touch it!

Unless VMware advise you otherwise!

so why give me the option to upgrade it?

it gives an option to upgrade ANY VM, which virtual machine version is lower than the current for the ESXi OS.

vSphere has no idea, what the VM, Guest OS is, and whether upgrading the VM, will cause any issues, it's not that intelligent, and KNOWS what the Guest OS or Appliance is!

Same is true for VMware Tools in a appliance, that does not match the host OS version, it will also ask you to update!

Whatever you do to the appliance, which is different to how it's been supplied is unsupported, if you change it and it breaks....VMware Support is unlikely to support you.

There are options to upgrade many things.... but you have no idea whether the upgrade will be detrimental to the OS.
