mixing ESxi host version in vCenter6.0

Have a question about mixing esxi hosts version in vCenter.
Plan to install a new center ver6.0 , Can I have esxi ver6.0 and ver5.1 in the new cluster?
Is there any problem  if i do not upgrade the vm hardware provided I upgrade the vmtools to latest?

Yes, vCenter Server 6.0 can manage mixed host versions e.g. 6.0 and 5.1.

The only issue which can occur, is the virtual machine hardware version 11 is not supported on ESXi hosts 5.1.

So keep that mindful, when creating VMs, if you want them t move around the cluster.

VMware Tools again, are linked to the ESXi host version, so technically VMware Tools from ESXi 6.0 is not technically supported on a VMware ESXi 5,1 host,

So be mindful of upgrades to virtual machine versions (11) and VMware Tools upgrades.

There will be a time VM can be migrated to older esxi or new esxi host incase of esxi host failure , this case the vmtools  is going to be out of date, does this matter?
I am not going to upgrade the vm hardware , using the NFS so it does not matter.

Sara2000:  That should be fine - That's what Andrew was warning about, but it will work fine.  In your case, it's probably better to leave the VM Tools at the 5.1 host's level, so they will work, but just show out of date from the perspective of the 6.0 host.  It sounds like you're planning this to be more long-term, but the situation you're planning is a typical state for an infrastructure in an upgrade process to be in.  It should work that way indefinitely if needed..

Today I put esx5.1 and6.U togther , moved vas to new esxi. I noticed that ping response was delayed.
I upgraded the vmtools and rebooted , then ping response was quicker.
The vms has latest vmtools, i hope  that vmtools should be backward compatible and would not give any issue until i finish with rest of the upgrade.

Should be okay, but as I said not supported.

but just the same as if you had out of date tools - not supported.
