SUSE Manager Main Page

The recommended order for migrations is to first migrate the SUSE Manager server and then the proxies.

Preliminary Considerations

Note: A SUSE Manager Proxy 3.2 is compatible with SUSE Manager 4. After the server has been migrated to version 4, proxies can be automatically upgraded from the SUSE Manager server using YaST autoinstallation.

NOTE: Migrating SUSE Manager Proxy 3.2 only works for proxies that have been registered as traditional clients. Proxies that are Salt minions cannot be migrated to the new version this way.

Upgrading SUSE Manager Proxy In-place

Procedure: Preparing to Upgrade

• Create an autoinstallation distribution based on SLE 15 SP1. This is required because SUSE Manager Proxy 4 is based on this version. For information on creating an autoinstallation distribution, see the Reference guide (menu:Main Navigation[Systems > Autoinstallation > Distributions]).
• Create an autoinstallation profile. The next section includes a template autoinstallation profile for your use. In this example, the label proxy4 is used for both the autoinstallation distribution and for the autoinstallation profile. Replace the label proxy4 with the one you use for your autoinstallation profile.

Autoinstallation Profile

Use this autoinstallation profile as an example.

Before proceeding make sure all the channels referenced in the autoinstallation profile are available and fully synchronized.

Running the In-place Upgrade

• In the SUSE Manager Web UI, upload the edited autoinstallation profile to your SUSE Manager server (menu:Main Navigation[Systems > Autoinstallation > Profiles]).
• In the Kernel Options field, enter this value:

autoupgrade=1 Y2DEBUG=1

The debug setting is not required but can help with investigating future problems you might encounter. The autoupgrade parameter, however, is mandatory.

• Select the proxy from the system list in SUSE Manager, click the Provisioning tab, and select the profile you created earlier.
• Click Start Autoinstallation. The system will download the needed files, change the bootloader entries, reboot, and start the upgrade.

Cleaning Up After the In-place Upgrade

After the proxy has completed the automatic upgrade process, it still will have the old channels from SUSE Manager assigned. If the proxy reports that there are updates available, do not apply them. Select the proxy from the system list and click change channel assignment. Clear the old channels and assign the new ones, which have been used for the upgrade.

All the clients connected with the previous SUSE Manager Proxy can access the SUSE Manager Server again and the proxy itself can be managed by the server as before.
