I use vSphere 5.5 U1 and some VMware Appliances. After Upgrade from 5.1 U1 to 5.5 U1 I begin to upgrade the Hardware Version and VMware Tools of the VMs. Now the Question is if I should upgrade the VMware Appliances or not? I know to not upgrade the Hardware Version from the vCenter Server Appliance because of not editable with the GOOD! old vSphere Client. Whats about the other VMs and the VMware Tools?
My VMware Appliances:
VMware vCenter Server Appliance 5.5 Update 1b (VM version 9, VMware Tools version: 2147483647 (3rd-party/Independent))
VMware vSphere Data Protection 5.5.6 (VM version 7, VMware Tools version: 2147483647 (3rd-party/Independent))
VMware vCenter Orchestrator Appliance 5.5.1 (VM version 7, VMware Tools version: 2147483647 (3rd-party/Independent))
VMware vCenter Operations Manager Foundation 5.8.2 (VM version 7, VMware Tools version: 8384
