Initrd does not include the xen drivers. You need to regenerate and you will be fine.
boot with sysrescue CD, and in a chroot olt environment you can create a new initrd with the xen drivers.
Thanks. The problem is taht we dont have a NFS datastore to use. So we had to do export/import.
you can migrate without a NFS datastore, but on esxi 6.5+ , you'll need to shutdown the VM before starting the migration
and with vsan there is an additionnal , slower steps : extractig the vmdk to a Remote (in XO )

Thank you. I will review the documentation again to confirm the number of ports needed for the storage networking as a different set of adapters from the VM networking.
