Personally Iāve never had any issues with upgrading Debian.
That being said, @dibs, why not just use the āTransfer virtual serverā feature from the source server?
Then you wonāt have to do any of that manually and everything ājust worksā
@Dibs: Your opinion is good, but not very fast I think, you also need a new server with a new IPā¦
I understand your idea of migrating everything to a new Debian 11 server, but I want to keep the same server with the same IP and my Webmin DNS cluster of 4 servers too.
@toreskev: Thatās a really great solution! much faster and automatic: but you also need a new server with a new IPā¦
Do you think it is possible to upgrade from the same server from debian 10 to debian 11 and therefore keep the new IP and therefore the same server name so as not to have to update the DNS servers on all domains hosted by this Virtualmin server?
@alexafi - I donāt know anything about Webmin clusters. Other types of clusters, many a time Iāve removed a node from a cluster when it is being upgraded (however you do that), upgrade it and then re-join the cluster. Thatās my preferred method.
I donāt know how straightforward it is to remove existing nodes and add "new"ones into a Webmin cluster.
As for the specifics here - if the servers are virtual, most times you can power down the original server and assign itās IP address to the ānewā server. If the servers are virtual - no real issues doing this. If your servers are bare-metal, then it isnāt so easy, i.e. noticeable costs.
Sorry for the late reply.
I donāt know regarding the cluster, but I honestly can not imagine it would pose much extra difficulties.
My current server main production server has been upgraded since Debian 8 and apart from some small niggles each time (not necessarily related to Virtualmin packages either) itās always been a smooth upgrade
Just make sure you have a backup or preferably a snapshot in place before attempting the upgrade.
Yes, as far as Iām concerned, itās Proxmox VMs with Proxmox Backup and webmin backup + Virtualmin (belts, suspenders, parachute in case of problems).
Hi Kev , Thank you for your message, on my side I stay on debian 10, but I think to start from a new fresh installation of debian 11 with the same ip configuration and restore the virtualmin backup.
I think I can afford it because itās virtual servers for my case.
Hello Kevin, so youāre going to do like me?
Complete reinstallation of the server in debian 11 and virtualmin restoration? (I wonder if emails are saved with this)
I think you have to test before you get boredā¦
