Service Pack migration not possible in SUSE Manager when LTSS is active

When trying to upgrade a system by performing a "Service Pack Migration", this is not possible if the LTSS product is activated in the source SP, but not available in the destination SP (which is the regular use case).
Latest versions of SUSE Manager will throw quite a verbose error. This is an example of a migration from SLES 12 SP3 to SLES 12 SP5, for which the LTSS does not exist yet. A SUSE Manager 4.1 would show this message when navigating to the SP Migration tab:

There is no migration available for this system. For some of the installed extensions no successor could be found:
SUSE Linux Enterprise Server LTSS 12 SP3 x86_64

Older versions of SUSE Manager might not show so much detail and simply omit which one is the conflicting product.



With SUSE Manager 4.3, this cleanup process is no longer necessary. It is now possible to migrate products even if the target product doesn’t have some of the successors, such as an LTSS product. See the SUSE Manager 4.3 release notes:

This problem is not specific of SUSE Manager, however the resolution is a bit different here.

First of all, the LTSS updates channels needs to be removed from the affected server(s). Easiest way to achieve it would be from the web-UI, navigating to the "Software" tab of the affected system(s), software, software channels and the LTSS channel can be easy deselected from here.

Secondly, the release packages need to be removed from the server manually. This can be done also from the web-UI, in the software tab, packages, list/remove. Here it is possible to filter in the search box by name, an appropriate search would be "ltss", and the packages to be removed are:
It is also possible to simply remove them with zypper:
zypper rm -y sles-ltss-release sles-ltss-release-POOL


The LTSS product is not available in the target service pack, so it needs to be removed from the source service pack first.

Additional Information

SUSE Manager 4.3 release notes:

SLES12-GA with LTSS might show an available migration path to SLES12-SP1 with LTSS.
However, from SLES12-SP3 with LTSS there are no available migration paths.
Removing the LTSS repository from SLES12-GA will allow migration directly to SLES12-SP2/SP3.
