In normal way to migration VM for new version to old one like this,
1.Boot Acronis True Image from CD , to backup Linux server(Ubuntu 16.04.5 LTS) at Xenserver 7.1.
2.Restore Backup image to Xenserver 6.5.
3.Finetune VM system and work.
It’s a V2V process, and it’s work for my Windows Server. but I got failed message as below.
Failed to start Create Volatile Files and Directories.
See systemctl status systemd-tmpfiles-setup.service for details.

I find the way to migration VM , and work well.
Export OVF format from Xenserver 7.1 and import it to Xenserver 6.5.
It tooks a lot of time to export and import, but it’s work.
