OpenStack Server Setup

I have a virtualization server with Proxmox VE on it right now, and it does great. It's an FX-6300 with 8GB RAM and a 1TB drive. I have heard a lot of good things about OpenStack, and I have been thinking about upgrading. I think I have the network capability, I have a single 8 port managed switch and a PFsense router. However, I want to know if there is a way to save all the VMs I worked so hard to get working. (for example the DNS server that literally took me WEEKS to configure)

Anyone have any ideas?
