I use ghettovcb to back up to shared/mounted NAS. i've tried to copy the VM using OVFTOOL but it won't boot. I've also tried to copy the VM from the back up location to the new ESXi 8.0 server, registered the VM - but it still won't boot.
Obviously they're different models of server should that matter - IDK.
and yes, https://williamlam.com/2012/06/how-to-copy-vms-directly-between-esxi.html. is exactly what I tried. no bueno...
