I’m getting a bit desperate here trying to migrate CentOS 7 server to AlmaLinux 8. Thisi is btw done on Hetzner cloud server, which is running KVM hypervisor (https://docs.hetzner.com/cloud/technical-details/faq/).
I thought some of you may have seen this. I’m not suspecting Virtualmin/Webmin to cause this, but well, what do I know.
I have managed to run the “leapp upgrade” succesfully. On the console screen I give reboot command and get the kernel menu with “ELevate-Upgrade-Initramfs” selection, as expected. After selecting it the reboot and migration continues for some 80 seconds and then… a complete freeze. The last texts on the screen are “Stopped target [this-and-that]”, like “Stopped target Paths”.
So, no luck so far.
Any pointers, any ideas? Is there something I’m missing?
Thanks, More / Helsinki
I think it’ll be better if you ask in the AlmaLinux forum, as it seems it isnt related to Virtualmin/Webmin
Centos upgrades have never been great, I would never do it. Fresh install using VM restores has always worked fine for me. Like vtrh said this is really not a VM issue as it just a control panel.
I’ve had no problems with Rocky conversions and upgrades on a half dozen or so systems. I haven’t done any Alma conversions, so I don’t have any experience. You may find the Alma community is better able to help with that.
Thanks! Yes, I’ll keep on asking from Alma and Hetzner forums.
I didn’t get any good advice from Alma or Hetzner forums, so I changed the tactics.
- Backed up all the sites and took notes of all generic settings (e.g. firewall ports).
- Moved the backup files to another server with SCP
- Rebuilt the server with AlmaLinux 9
- Did basic hardening for the server (SSH port access, firewall etc.)
- Installed Virtualmin
- Moved the backup files back with SCP
- Restored the sites
It went pretty well. This guide was really helpful:
I will handle my other servers with the same procedure.
