vMotion between two hosts with different version?

Jump to solution


Hi,

Can we vMotion VM's between two hosts with different version? For example, vMotion a VM from esxi 6.0 to esxi 5.5, or  from esxi 5.5 to esxi 6.0.

Thanks.

Yes, it will prevent you from moving it.

Hi,

yes you can do that.

Otherwise you would have a problem when upgrading hosts Smiley Happy

If i vMotion the VM from ESXI 6.0 to ESXI 5.5, is there any virtual machine hardware version compatibility problem ?

For example, hardware version 11 is supported by ESXI 6.0, but is not supported by ESXI 5.5, can i vMotion a VM with hardware version 11 from ESXI 6.0 to ESXI 5.5 ?

Hi,

your hardware version 11 VMs can only run on ESXi 6.0 and later. So only upgrade the VM hardware after all hosts are upgraded.

If you have some v11 VMs that have to run on ESXi 5.5, there are ways to downgrade the hardware version:

What will happen ?  If i have a VM with hardware version 11, and i attempt to vMotion it to a ESXi 5.5 host, will vCenter prevent this action?

Hello,

You may also want to check out http://www.astroarch.com/2012/01/vsphere-upgrade-saga-all-about-evc/ for some ideas on how to setup EVC without needing to reboot your nodes. There are ways to make that happen.
