The warning message above got a face lift recently thanks to the vCenter 5.5 Update 2 released on 9/9/2014. According to the release notes you’ll no longer see the “You cannot use the vSphere client to edit the settings of virtual machines of version 10 or higher. Use the vSphere Web Client to edit the settings of this virtual machine.” Unfortunately there is still a pesky dialog box, and there doesn’t seem to be a way to disable it. However, the message, while a bit nagging, is a welcome change to the depreciating vSphere client.
The new message warns users “You are about to edit a virtual machine of version 10 or higher. Only version 8 features will be available for Edit using this client.” This is a fair trade-off as you can still do a majority of your day-to-day tasks. You’ll loose things like the ability to crank your vCPU count above 32 or adding a SATA controller but most users will be OK with that.
Windows XP & Vista users need not apply. Starting with vSphere 5.5 Update 2, Windows XP and Vista are no longer supported to run the vSphere Client.
