Can I upgrade my VMware 6.0.3 without losing my data? I already upgraded to Yosemite

I have VMWare Fusion 6.0.3 and I upgraded to Yosemite. Oops. I can't open VM because its not a compatible version. Can I still upgrade the VM without losing my data?? I really need to NOT lose my data. Note: I did not backup my computer before this...
