Server - Minor Version Upgrade with Zypper

To perform the upgrade with Zypper, use the Zypper migration tool.

Before upgrading from SUSE Manager 4.0 to 4.2, ensure you do not have any unpublished patches. Check for unpublished patches by navigating to Patches Manage Patches Unpublished. You must publish or delete them before you upgrade.

For more information, see https://www.suse.com/releasenotes/x86_64/SUSE-MANAGER/4.1/index.html#_dropped_features.

Procedure: Upgrading with Zypper

From the command prompt, as root, ensure the spacewalk services are not running:
```
spacewalk-service stop
```
Launch the Zypper migration tool:
```
zypper migration
```
Zypper will show the possible migration targets with detailed summaries.
Select the appropriate target, and follow the prompts to complete the migration.
Reboot the server.
When rebooted the SUSE Manager spacewalk services are not running until you have migrated the PostgreSQL database to version 13.
Log in on the text console as root. If you are upgrading from 4.1 to 4.2, run the database migration script:
```
/usr/lib/susemanager/bin/pg-migrate-12-to-13.sh
```
If you are upgrading from 4.0 to 4.2, run the database migration script:
```
/usr/lib/susemanager/bin/pg-migrate-10-to-13.sh
```
Ensure the spacewalk services are running:
```
spacewalk-service start
```
spacewalk-schema-upgrade is not needed anymore. It will be run during spacewalk-service start automatically.

If the process fails, check these issues first:

If Zypper does not have the migration tool available, install the zypper-migration-plugin package.
If there are older updates available, Zypper will notify you and ask to install them first. You must install all updates before performing the upgrade.
