We have run up the 7.0.1 appliance in a VM (ESXi). I am now looking at upgrading the appliance to 7.0.2

According to the docs there are 2 ways to upgrade.
1. Side-by-side
Install a new 7.0.2 vm, then run the upgrade option on the live appliance, pushes everything over to the new vm

2. In Place
Install a new VM, then run the upgrade option on the new appliance, pulls settings over

It seems to me that in-place isn't really in-place, one is 'push' to new VM, the other is 'pull' from existing vm.

Is there no way to do a real 'in-place' upgrade without creating a new VM at each version update? Or am I missing something?
