Move configurations to a new PBX machine (both running

I’m running my current PBX box on a physical machine and I’m planning to move the PBX to a VM (ESXi 5.0),
Both machines are running PiAF purple with latest updates and FreePBX

What is will be the safest way to move all my configurations to the new box?

Many thanks!

Wouldn’t you do a full backup from the first box then a full restore to the second?
