TADDM 7.3.0 FP7 - Problems with discovery after installing Fix Pack 7

Problem

Unable to start discovery run after migrating to new TADDM fixpack

Symptom

When attempting to run a discovery on any of the Discovery Servers after migrating, the following error occurs:

MESSAGE OF ERROR:
=================
CTJOX0991E THE REQUESTED OPERATION CANNOT BE PERFORMED BECAUSE A
DATABASE MIGRATION IS IN PROGRESS.

Diagnosing The Problem

Check migration.log to ensure no errors occurred during the fixpack application. Check in the end of the migration.log for the following statement 'completed successfully'. If there are no error's and the migration did complete successfully, TADDM has only failed to move the 'in progress' status of the migration to 'COMPLETE'

Run the following command to resolve the issue, according to the operating system, to change
the upgrade status to COMPLETED, which enables the TADDM processes to operate:
For Linux and UNIX systems:
