Importing Previously Saved Whonix VM Backups?

Hello All,
For some time I’ve been running Virtualbox and Whonix on a host PC with Ubuntu 14.04. With Virtualbox I exported backup copies of my Whonix Workstation and Whonix Gateway VMs. If I use Virtualbox to import those saved VMs on a different host PC running Ubuntu 16.04, will the Whonix VMs run o.k.?

Can be sorted out as per:
