Copy or move VM to a new Mac

[Mac Frank]

I recently bought a new MBP and I have to copy or move the VM from the old one.
I'm quite sure I read a post or a how to about this topic but I cannot find it now.
Could someone please address me to this post or how to?
Thanks

If the VMs were created using VBox v4 or later then the procedure is simple: copy the VM folder(s) to the new host, run VBox and use Machine|Add to register them.

I think they were created with Vbox V4, but how can I check it out?
Any setting or property or information can help?

If the VM settings file has the .vbox extension then it's a v4 format VM. Another sign is that all VM related files (.vbox, .vdi, Logs) are stored in one folder called <vm name>. There's also the fact that the <vm name> folder is usually (but doesn't have to be) stored inside a default container folder called (on Mac hosts - I think) "VirtualBoxVMs".

The old v3 layout was unmistakeably different: VMs described by a <vm name>.xml file, which is stored in .VirtualBox/Machines/<vm name/, hard disk images stored in a separate folder .VirtualBox/HardDisks, used by all VMs.

If your VM used the old v3 layout then it's best to clone it on the original PC first: the clone will have the v4 layout. It's also possible to convert the layout manually if you really know what you're doing.
