Please share a copy of /var/log/distro_migration.log
Yes, of course - but it did not help me ….
It looks to me that the SUSE developers took a clean server and didn’t test it once on a server with a “history”. With “history” I mean, that the server has been upgraded from SLES 12 step by step, so it got some old data because of previous upgrade-processes which seem to be “unclean”.
Also, the documentation how to upgrade is simply wrong. I mean the SSH part. Without the help of @aalzayed I would be stuck.
I wrote my own step-by-step guide which I will publish within the next couple of days.

There is no indicator why system canceled the migration process. If you can share a supportconfig, this would be good.

Thanks for sharing supportconfig.
I think migration is failing because /var is on separate disk:
# /bin/df -Th
Dateisystem Typ Gr?sse Benutzt Verf. Verw% Eingeh?ngt auf
/dev/sda1 xfs 40G 2.7G 38G 7% /
/dev/sda3 xfs 40G 13G 28G 31% /usr
...
/dev/sda7 xfs 71G 2.3G 69G 4% /home
/dev/sda8 xfs 40G 887M 40G 3% /tmp
/dev/sda6 xfs 40G 4.6G 36G 12% /opt
/dev/sda5 xfs 40G 2.0G 39G 5% /var
The operating system needs to reside on a single partition. Support for multiple partitions, such as LVM, is limited to configurations where the separated partitions do not contain OS-critical data or processes. For example, a separate /home partition will function whereas a separate /var will not.
Let us try again, please try again the migration and once it failed share:
cat /etc/issue
Also, you can add:
debug: true
verbose_migration: true
to: /etc/sle-migration-service.yml file and then trigger the migration. Let me know the result.

I created the /etc/sle-migration-service.yml file (it didn’t exist) with the proposed content, also added “PermitRootLogin yes” to /etc/ssh/sshd_config.d/50-permit-root-login.conf and started migration again. After reboot I can not login into the server with ssh though - now I must wait until friday to log in locally on the server …
Thanks!
This is what I meant that there is an error in the documentation regarding SSH. It doens’t work but I was a lucky guy because I had from another VM an existing connection, so I could log in and install the package which @aalzayed suggested in my thread.
The correct way is to check before you run the migration if you can log in via ssh root@hostname to the server which is going to be migrated.

however passwored-less ssh login should still works. But I’m with you, the upgrade doc should mention it. By the way, suse-migration-pre-checks command print a hint 
Is it pingable? Have you tried: ssh migration@IP_OF_INSTANCE
No, it is not pingable …
And yes, i have tried to connect with “ssh migration@…” - No route to host
If it is not reachable, then you need to check the console.
Of course, but today it is not possible - tomorrow!
Thanks!
So, after reboot I ‘ve tried (as suggested in above link) :
zypper in openssh-server-config-rootlogin
“Paket ‘openssh-server-config-rootlogin’ nicht gefunden.”
I mean the upgrade doc should be definitely corrected!
Server ist still on SLE15 SP7 and I can log in as root with ssh. Here is the last /var/log/distro_migration.log:

I’m not sure why the migration is not working.
But can you give it another try? remove: kernel-default-devel package
rpm -qa | grep kernel-default , on my system show only kerne-default.
Let me know the result.
If this didn’t help. Please remove the log file and then: add the file /etc/sle-migration-service.yml and add
debug: true
With the debug switch set the system will not reboot in case of an error and you can check what was wrong inside of the live migration system by ssh via migration user. Check the failed services: systemctl –failed
let me know the result.
