This document (7024109) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 15
SUSE Linux Enterprise Server 12

Situation

The Online Migration (Rolling Updates) is failing with the following error message:

"Multiple base products found"

For example, migrating SLES 15 for SAP to SLES 15 SP1 for SAP:

ha2:~ # zypper migration
.....
.....
.....

All repositories have been refreshed.
Can't get available migrations from server: SUSE::Connect::ApiError: Multiple base products found: 'SUSE Linux Enterprise Server for SAP Applications 15 x86_64, SUSE Linux Enterprise Server for SAP Applications 15.1 x86_64'.
'/usr/lib/zypper/commands/zypper-migration' exited with status 1

Resolution

To fix this error run SUSEConnect --rollback.

Alternatively, de-register the system first, and than re-register the system once again, in order to continue the migration.

Cause

The system was already previously migrated to SP1 and rolled-back later, or a previous migration may have been interrupted .
