Distribution Upgrade and Server Migration

1. Verify Current Product Status

   SUSEConnect --status-text

   Confirm:

   • Base OS: SUSE Linux Enterprise Micro 5.5

   • Extension: SUSE Manager Server 5.0 Extension

2. Ensure System is Updated

   transactional-update patch

   • If patches were applied, reboot the system before proceeding to migration:

   reboot

   • If no updates were found, you can proceed directly to the migration step.

3. Start the Migration:

   transactional-update migration --auto-agree-with-licenses --gpg-auto-import-keys

   Follow the prompts and select the available migration to SUSE Linux Micro 6.1 and SUSE Multi-Linux Manager Server Extension 5.1.

4. Reboot to Apply Changes

   reboot

5. Post-Reboot Checks:

   Verify upgraded OS and SUSE Multi-Linux Manager extension:

   cat /etc/os-release
   SUSEConnect --status-text

   You should see:

   • SL-Micro 6.1

   • Multi-Linux Manager Server Extension 5.1

6. Enable Root SSH Access (if required). SL Micro 6.1 disables root login via SSH by default. Edit /etc/ssh/sshd_config.d/sshd.conf:

   PermitRootLogin yes

   And restart the service:

   systemctl restart sshd

   For more information, see Remote root login on SL Micro.

7. Upgrade Server Containers

   mgradm upgrade podman

   Follow the prompts to pull and configure the new 5.1.0 containers.

   SUSEConnect --product Multi-Linux-Manager-Server-SLE/5.1/x86_64 --regcode <your-regcode>
