Environment
=========
All

Version
=======
BC 5.3.x

Cause
======
The migration code will perform an upgrade on schemas if the following conditions are met:

1). The database specified in TIBCO BusinessConnect 5.1.x or 5.2.x configuration is up and running.
    
2). The username and password are identical.

3). The old database schemas are not removed.
    
4).  The audit, non-repudiation and runtime handles are not different from the configuration store handle.

If any of these requirements are not met the reported error will be seen.

Resolution
========

As a workaround create the schema tables manually. To manually update tables for audit logs, non-repudiation logs or runtime tables do the following:

1). Go to System Settings -&gtJDBC Configuration.

2). Click on 'Create Audit/ NR/runtime tables' so that all Audit/NR/Runtime tables will be dropped and recreated.
