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 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 90 seconds and then… a complete freeze.
So, no luck so far.
Any pointers, any ideas? Is there something I’m missing?
Thanks, More / Helsinki
looking at the error message you’ve got something setup to prompt for a luks password which is waiting for input. you could just try typing the password…
Thanks for the tip, sej7278. Though it didn’t help.
I changed the tactics. Sharing my resolution here, if someone else is having the same problem:
I’m using Virtualmin/Webmin management software in my server, so this procedure seemed a good plan-B:
- 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 well. This backup/restore guide for Virtualmin was really helpful:
I will handle my other servers with the same procedure. Also the one with cPanel, which should be able to handle backup/restore quite well.
