We have a cluster running several ESXi 5.1 hosts and one ESXi 5.0 host. The VM's running on the 5.1 hosts show their VMWare tools as outdated, but the VM's running on the 5.0 show their tools as being CURRENT since with every new version of ESX, the VMWare tools also need to be updated. My question is: if we update the VMware tools on the VMs on 5.1, will those hosts be able to run on the 5.0 host if needed? This is a in cluster with HA/FT enabled, so hosts do automatically get migrated over to hosts depending on load/etc.
Any help is appreciated. Thanks.
