Configuration import verification

[EricPerl]

I've been running a virtualized proxmox for a few weeks now (very nice upgrade coming from TP-link).

I saw a recent post from @meyergru about recommended settings and thought I'd check them out.
If anything, that would be a good practice for future recovery...

I used scp to download the entire /conf folder (got some errors on ssh keys that I ignored).
I searched/replaced the passthrough NICs with bridge equivalents in the config.xml only (i.e. not the files in /conf/backup).
I made an iso out of the updated downloaded content that I made available to a new VM.
Creating the bridges over the NICs that used to be passed through was not fun (stopping the original VM was not sufficient. I had to reboot proxmox).

Anyway, I reran a full install and imported the configuration.
I'm reasonably confident that my core config was imported (VLANs, users, ISC DHCP, FW aliases and rules, Unbound block lists...).

But I was under the impression that:
* DHCP leases should have been imported too. By now most (if not all) devices have renewed with their existing IP but I checked right after the first boot and the list appeared small. Machines that I haven't booted since the install don't show up.
* The full history of configuration changes should be available as well. A bunch of files have been imported (confiXXX.xml naming scheme) but the only history that shows in the GUI is just 2 "new" files (config-1732751930.5814.xml and another).

So I now wonder how much I'm missing.
Is there a log of what the config importer did?
