It looks like something worked but admin UI is still not available.
We can take a look with a new pihole -d
token.
lighttpd
is still not running.

What is the output from sudo lighttpd -tt -f /etc/lighttpd/lighttpd.conf
?
It gives no output.
[pranav@PLEXVM ~]$ sudo lighttpd -tt -f /etc/lighttpd/lighttpd.conf
[pranav@PLEXVM ~]$
That's not good.
Try with just one -t
instead of -tt
[pranav@PLEXVM ~]$ sudo lighttpd -t -f /etc/lighttpd/lighttpd.conf
Syntax OK
[pranav@PLEXVM ~]$
That's better. The configuration is correct and recognized and that's about as far as we can go on our side.
The errors below are causing the crash. The errors indicate the problem is in an area that we are not using. I suggest a VM dedicated to Pi-hole and not one shared with other heavy services like Plex.

I understand. I have worked so hard on perfecting blocklist/whitelist on this install over a year. I can build dedicated VM and get it up and running in next 20 mins.
I just don't know how to migrate current block&white-list to new VM.
If you have script to export and import it, I would appreciate.
If I compare /etc/pi-hole directory on new server with old and sync delta, that should take care of white/block list.
Please correct me if there is risk with above approach.
In version 4 the lists are in /etc/pihole
but you'll have a better go using the teleporter
function. That will create an archive for you to export from the old and import in to the new.
If you are writing code for PiHole, please include adlists.list in teleporter
function.
Currently, it doesn't include it.
After building a new dedicated pi-hole VM, I come to learn this hard way.
Also if you could automate command to update gravity, it would be helpful to the next person who needs to migrate their white/blacklist to the new server.
In V4.x, the adlists.list file is included in the teleporter for export, but is not imported without operator action.
In V5.0 (currently at beta), the following is included in the teleporter.
