Upgrading from Snow Leopard to Yosemite

Hi All,

I'm currently running VMWare Fusion 4.1.4 on a Mac Snow Leopard, in order to retain access to a Windows XP Virtual Machine, which houses a quite ancient (but perfectly adequate) accounting program.

It's becoming more and more difficult to stay viable with Snow Leopard, so I'm going to upgrade it to Yosemite.

Assuming I do that, I guess I'll probably need Fusion 8, or somesuch to run Virtual Machines.

Of course there will be expense involved in upgrading Fusion, so before I buy it, I need to know:

will Fusion 8 still be able to open my dinosaur XP Virtual Machine.

All opinions gratefully received.
