[SOLVED] Restore to new instance of VE

Here's my story.
I installed and ran Proxmox 7 on a Dell Poweredge R710. Things were good and I hade about 6 containers and a couple of vm's. I realised how useful Proxmox was and my projects grew to the point that I had to upgrade the hardware. I ended up buying a better conditioned R710 with more ram and better processors. So, I thought all I needed to do was to swap out the HDD array and fire it back up and that would be that. Nope, after a bit of struggle I managed to reconfigure the network card so that I had the GUI again, but now none of the vm's or containers are accessible through their respective ip's, even though I can ping them just fine without loss. I can only imagine that there is a mess left somewhere because of hardware mac change or something.
Anyway, I did build a PBS and ran it for about two weeks backing up all of the containers and vm's. I chose to stop the containers and back up each time and scheduled a backup of all containers at midnight every day. No errors were recorded from the back ups.

So I'm thinking can I wipe my Proxmox VE and start again using the new hardware and then restore those backups to the new Proxmox VE. Or is there a better way?
Thanks for any input... I really appreciate it.

Whats your output of cat /etc/network/inferfaces and ip addr?

I'm at work at the moment but will do that when I return at about 11pm UK time :)
But I remember editing the /etc/network/interfaces in order to correct the right network card name. It was after doing that I was able to log in to the gui. There is only one nic plugged in.

As far as I can see the NIC eno3 is in use and the ip is 192.168.1.14/24 which is correct and the default gateway is also correct


That resolves to the router and I can access Proxmox VE through the GUI over the internal network. I understand that all of the vm's and containers use the vmbro to access the router and I can ping them successfully.
 
Jup, config looks fine. Are the guests setup to use static IPs or DHCP?
I guess you didn't changes your physical network setup and router and so on are unchanged?

I set up static ip's for the containers and at the router they are set for mac address. They all show in the ip table pool and the mac address for each container also shows up correctly.
So no the router hasn't changed and the firewalls are just the same as before.
 
I wanted to post the results of the weekend. It turns out that changing my NIC card dragged up a lot of problems. That said I can conclude that none of them were actually the fault of Proxmox VE, well not directly. What I did in the end was to reconnect the Proxmox Backup Server to a new instance of Proxmox VE and then restored the guests as "Unique" and then set up the NIC for each guest

Following the advice from:
Oguz
just add the PBS as a storage unit on your new PVE (Datacenter -> Storage -> Add -> Proxmox Backup Server) and enter the details of your existing datastore on PBS; nothing will be overwritten when adding the storage.

from there you should be able to restore whichever VM you need.

Then I simply set up new network settings for the guests and all worked fine.


The mess was caused in part with me changing the NIC but I also had Nginx acting as a reverse proxy for the other containers. The Ubuntu distro failed and I was left with a bit of a mess with dns issues.
So restoring guests from the backup was a life saver. I had to build the Nginx docker again, but I got off lightly I think.

Oh the restore took well over 4 hours ( there was a few TB's of data) and once you've committed a restore you must let it run its course. Unfortunately there is no progress bar, you you just have to trust the system.
