mgradm migrate podman <fqdn> fails with data in /var/cache/kiwi/zypper

[Martin-Weiss]

Just tried the migation of SUSE Manager 4.3.13 to 5.0.2 and ran into this error:

On the source we see this:

-> maybe we need to blacklist /var/cache/kiwi for the migration as well?

Workaround - on the source:

rm -rf /var/cache/kiwi
