move virtual machine in other server

Hi,

I have a server VMware (Esxi 6.0.0   2494585) with four machine (one machine is ubuntu and other machine centos)

I must migrate a new server with greater capacity (Esxi 6.0.0 3029758).

I export machine from first server (file-->export-->export ovt template.......OVA)

When restore machine in new server (Deploy OVF template), in two case the restore is oK.

In the other 2 case i receive the following message:

Failed to deploy OVF packadge. The task was canceled by user

Thank all for help
