Hello.
I am in progres of moving the virtual servers from the ESX4 platform to the ESXi5 platform. Som of the servers are already on the ESXi5 hosts. I did not upgrade the VMs hardware just yet. I would like to know if it will be ok to start using HA and DRS with the VMs which were migrated from ESX4 to ESXi5, before upgrading the VMs hardware and VMWare tools. The cluster conatins both, VMs with hardware version 7 and 8. Thank you.
