Use vmdk file from VMWare fusion 6

Hey,

I have trial version of Fusion 6 on my Mac and I am running windows 7 and Linux VMs. As trial time goes on, I start to think if I should prepare for the purchase or I need to switch to a different product.

ESXi Hypervisor is a good alternative for what I do normally with VMs. But it will take me a while to re-build VMs ....So I got this question in mind(even ESXi only support virtual machine version 8): can I upload the vmdk file I have from fusion 6 to esxi host and create VM with it?

Thanks,

Shuai
