How to Upgrade Proxmox 7 to 8

[@kezza4k]

Thanks David, super clear and easy to follow. You even talked through some issues that you didnt have but I did, so really appreciate that!

[@TechTutorialsDavidMcKone]

Thanks for the feedback. Good to know the video was helpful

[@romayojr]

thanks, david - this helped me upgrade my 3 node cluster from 7.4 to 8.1 successfully! i held off on upgrading for a long time until i watched your tutorial, well explained and so easy to follow.

[@TechTutorialsDavidMcKone]

Yeah, it can be nerve wracking compared to upgrading other hypervisors Normally you just point at a file and after a reboot, the new version is installed But Proxmox did provide a process and it works well So glad the video helped with your upgrade

[@jerometv7637]

Thanks a lot, just upgraded my ProxMox 7 to 8 with the help of your easy tutorial here :)

[@TechTutorialsDavidMcKone]

It is a big upgrade, so good to know the video helped

[@egysnet]

I have followed many explanations regarding Proxmox, but yours is the best. Please continue

[@howtoinvest4yourself241]

your content is super helpful as I am a complete noob and I am also a visual learner... I love being able to follow along in my lab with you as you did your upgrade... it worked with out issue.

[@TechTutorialsDavidMcKone]

Good to know the video was helpful I must admit, it would be better if this could all be done from the GUI But I suppose since Proxmox VE is based on Debian and different things need doing for different deployments, it may not be that practical

[@BlitzFingers]

Perfect! That covered every step of the way. I'm on 8.0.4 with your help.

[@TechTutorialsDavidMcKone]

Good to know if a video helped so thanks for the feedback

[@ThepvtBanner]

As a non linux user found the earlier vid on upgrading Proxmox 7 to the latest version pretty easy and follow this to get upto 8.0.3 was just as easy thanks. My 3 containers and 2 VM's came up no problems.

[@TechTutorialsDavidMcKone]

Good to know things went well

[@chocolateandy1963]

Spot on David. Another easy to understand and follow tutorial.

@dave Planning to tackle proxmox 8 SDN? There is no good video out there on it. Something in your usual deep dive will be really helpful.

[@TechTutorialsDavidMcKone]

It is something I'll be looking into although there are quite a few ways to implement it At the moment I'm trying to automate more things and put more services into containers But I'll get round to it

[@howtoinvest4yourself241]

how would you go about backing up your VMs on your older version before the upgrade if all your VMs are on your local hard drive and not connected to a NAS or SAN?... As far as everything else you have shared here it works properly as you shown here

[@TechTutorialsDavidMcKone]

An OS upgrade shouldn't impact the VMs Even if they introduced newer virtual hardware, it should be backward compatible at least for a while, similar to ESXi But if you wanted to backup a VM, you could always plug in an external USB drive Then run a backup job from the GUI and point it to the external drive I can only speculate where all the files are as I just use the backup tool There are config files, hard drives and snapshots that would need copying and they are kept in separate places So even if you connected in using SFTP for instance to copy them to you local computer, you'd need to know where everything is

Thanks.

[@fvgoya]

Thank you!!!!! Really helpful video.

[@TechTutorialsDavidMcKone]

Good to know the video was helpful At least future upgrades can now be done from the GUI for a while more

[@fvgoya]

@@TechTutorialsDavidMcKone that’s true! Thanks again, David!

[@zyghom]

super nice but... I missed the final: "see guys, the VMs and containers are WORKING after upgrade" ;-)

[@TechTutorialsDavidMcKone]

That would have been too helpful Part of the fun of upgrading things is wondering if they'll still work afterwards

[@zyghom]

@@TechTutorialsDavidMcKone my proxmox is on separate machine, lots of VMs and CTs there, one of theme is Home Assistant and all the necessary apps for it - I will wait with upgrade ...maybe till 2024 - I don't have a second machine to backup everything before backup.... ;-)

[@zyghom]

@@TechTutorialsDavidMcKone ok, why not to kill the weekend - upgrade to 8 done and ... "operation successful - patient... alive" ;-)

[@TechTutorialsDavidMcKone]

@@zyghomSo far I haven't run into problems upgrading Debian or Proxmox servers. Still got others to do so fingers crossed...

[@zyghom]

@@TechTutorialsDavidMcKone yeap, but you said and showed: yours is LAB so not much installed on it, no customisations etc. And there is no problem to lose the LAB one - worse when your home stops turning on the light because Home Assistant is down because Proxmox is down because "admin played upgrade" last night ;-)

[@owenjohnson5030]

I have a couple warnings. When I was first setting up this server I was a noob, (still am). I crated a zfs pool on a drive. I then wiped the drive completely and created a new pool. I'm now getting the following "WARN: storage 'zfs4tb' enabled but not active!" How do I get rid of this completely?

[@TechTutorialsDavidMcKone]

If we're talking about a zfs pool you no longer need I would think you can delete it in the GUI Navigate to | Disks | ZFS and remove it from there If that doesn't help then you can open a shell on the server or SSH into it Type in zpool status That should list the state of pools including the names of the drives being used It's best to have an empty pool before you delete it To remove a drive from a pool you can use this command zpool detach To delete a pool it's this command zpool destroy You might need to add the -f parameter to force its removal e.g. things are messed up and you can't remove a drive
