Resolution

This issue was reported to SUSE Engineering and the package version SLES15-Migration-2.0.40-6 from the Public Cloud Module 12 x86_64

was officially released to get this issue fixed.

Note: The migration target will be SLE 15 SP3

Cause

The issue was that the regionService directory has moved from /var/lib/ to /usr/lib/ but
the DMS scripting was only looking for the certs directory under /var/lib/ when attempting to setup the bind mount into the ISO runtime environment.

SUSE Engineering has fixed this issue.
