Hi @Jamie and/or other @staff or other @staf
Given the fact that I am in the UK, it is around 11 PM here and I am not sure when I might just fall on my desk as I have not slept properly in the last 3-4 days. Plus because you are in the US and you are online + working on Sunday (I sincerely appreciate you replying back to me) I would appreciate it if we can get this resolved tonight because it’s a weekday tomorrow and that too Monday. 
And so I am taking the liberty to add few more issues to the question (as you scroll down)
Just to give you some background:
1.>
To start with, I restored 40 domains in total and Yes absports.co.uk was part of it. But it is a disabled domain. I had it earlier and then redirecting it to another website. But now we do that directly from the domain registrar (GoDaddy) so this was not needed anymore.
There are 2 more such websites (disabled and redirected from registrar level) but as you can see none of them threw any error. However, just to add yogasanskriti is also a disabled domain - this project as supposed to start last year but due to Covid did not kick-off, so we disabled it (the website does not exist)
Worst case scenario I can simply delete these 2 domains and start from the scratch - just to avoid any delay and headache, but just wanted to understand what happened here and why and how to deal with it in future and because I ran of ideas and any support, I opened this ticket with you.
Having said that the error that I am getting with esspl domain critical.
esspl.co.uk is our OWN, main and core business website with few subdomains for our internal project/application. astro.esspl was created wrongly, it should have been astro.esdev and should have been on test environment.
So again I can transfer content, delete it and start this in the test environment. But when I tried that in my last attempt it messed up esspl.co.uk (which is super critical for us) and so I am not confident to do that again and therefore opened this ticket with you.
Pls see the error below:
(astro.esspl.co.uk), zone Elegant Systems - Where Technology Must Bring Value for Money, Cloud | Microsoft Partner | Sharepoint loading from master file /var/lib/bind/esspl.co.uk.hosts failed: not at top of zone, zone Elegant Systems - Where Technology Must Bring Value for Money, Cloud | Microsoft Partner | Sharepoint not loaded due to errors.
The funny thing is: right now everything is launching and opening perfectly fine, but somewhere in my head I am not comfortable running the Configuration Check and getting errors and Virtualmin categorically saying that my system is NOT ready. Plus I am worried that it will create problems at some point in time and so I want to be double sure before I proceed any further.
As per your request, the output of /var/lib/bind/absports.co.uk.hosts is as follow:

Also in my last 3 attempts while running Post Installation Wizard I always got ClamAV error saying it cannot connect with /var/run/clamav.clamd.ctl and it will not show up in the dashboard so I had no choice but to ignore it and after some time it will automatically starting showing up - not sure how and why.
Also, just so you know at the end of the install wizard, I choose No default virtual server and SSL enabled with Let’sEncrypt. Hope that’s not creating any issue. Right? I used to have Virtualmin’s Letsencrypt SSL but now I use free SSL from Cloudflare. Pls see the screenshot below with my choice/preference:

Also while configuring the new server, as per Ubuntu suggestion I have assigned 1 GB to /boot portion which is 83% used, but when I look at the old configuration I have given 10 GB to /boot partition and even that was 93% used after a while (almost 12 months), pls see image below for both situations and do let me know your recommendation.
Pls see the Old config below:
Pls see the New config below:
4.>
Also when compared to old vs new setup/configuration, I am missing PHP-FPM 7.2.* Server, PHP-FPM 7.3.* Server, PHP-FPM 8.0.* Server. Any reason why? What impact it can have and how I can enable it on the new system? Pls see the screenshot below:
5.>
And lastly, how can I get rid of DNS registration expiry error. This is a live and customer’s website. Pls see the screenshot below:
Many Thanks,
Ravi
