Unable to migrate from SUSE Manager 5.0.x to MLM 5.1 when using signed certificates

SUSE Multi Linux Manager 5.1

When trying to upgrade a SUSE Manager 5.0 to SUSE Multi-Linux-Manager 5.1 with the below command:

mgradm upgrade podman \
 --ssl-db-ca-intermediate /root/Certs/inter.pem \
 --ssl-db-ca-root /root/Certs/ca.pem \
 --ssl-db-cert /root/Certs/server.pem \
 --ssl-db-key /root/Certs/server.key

The upgrade could fail with the below error messages:

1:26PM ??? Cmd output > time="2025-08-08T13:26:39+02:00" level=warning msg="Path \"/etc/SUSEConnect\" from \"/etc/containers/mounts.conf\" doesn't exist, skipping"

Check if a file named /etc/SUSEConnect does exist

ls -la /etc/SUSEConnect

If the file does not exist, create it:

touch /etc/SUSEConnect

Afterwards repeat the migration command.

The issue will be fixed with the release of the SUSE Multi Linux Manager extension 5.1.1.
