Description of problem:
Going to "Your Organization -> Configuration" (/rhn/multiorg/OrgConfigDetails.do) results in ISE on my Satellite upgraded from 5.7 Ora to 5.8 Emb on s390x.

I think used schema upgrade path looks fishy (but maybe it is okay to start with 5.8 after Ora->Emb migration):
===================================
# spacewalk-schema-upgrade
Schema upgrade: [satellite-schema-5.8.0.17-1.el6sat] -> [satellite-schema-5.8.0.18-1.el6sat]
Searching for upgrade path: [satellite-schema-5.8.0.17-1] -> [satellite-schema-5.8.0.18-1]
Searching for upgrade path: [satellite-schema-5.8.0.17] -> [satellite-schema-5.8.0.18]
The schema version is the same, except for the dist tag.
Searching for upgrade path: [satellite-schema-5.8.0] -> [satellite-schema-5.8.0]
The path: [satellite-schema-5.8.0]
Planning to run spacewalk-sql with [/var/log/spacewalk/schema-upgrade/20170112-084226-script.sql]

Plase make sure you have a valid backup of your database before continuing.

Executing spacewalk-sql, the log is in [/var/log/spacewalk/schema-upgrade/20170112-084226-to-satellite-schem
a-5.8.0.log].
The database schema was upgraded to version [satellite-schema-5.8.0.18-1.el6sat].
