Resolution

This issue is reported to SUSE Engineering until a permanent fix is available the following workaround can be used:

1- Create the old/previously used directories: "/var/lib/regionService/certs"

2- Copy the cert files

3- Modify "/etc/regionserverclnt.cfg" and set "certLocation" -> to the previously used path "/var/lib/regionService/certs"

4- Install the latest "SLES15-Migration" package

5- Trigger the Migration executing: "sudo run_migration"

sles-sap-12-sp5-gen2:~ # mkdir -p /var/lib/regionService/certs

sles-sap-12-sp5-gen2:~ # run_migration

Cause

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

SUSE Engineering is working to get this fixed.
