OnCommand Performance Manager migration to OnCommand Unified Manager fails


Background: 

Recently, the OnCommand Unified Manager (OCUM) was upgraded to 7.2. After upgrade, OnCommand Performance Manager (OCPM) data from 7.1 instance was migrated to OCUM 7.2.
The following document was used to perform the migration.

Issue: 

The migration process was reported as FAILED . One easy way to find out what caused the failure is to re-run the migration. As you re-run the migration, the workflow will show what caused the previous job to fail. Please note the cause of the failure

Alternatively, you can generate a support bundle (KB is here) and review the migration.log under JBOSS directory of the support bundle.

Resolution: 

Based on the cause of the failure, you can use one of the following KBs:


Migrating performance data to OnCommand Unified Manager 7.2RC1 shows status 'FAILED':

Performance data migration fails between OnCommand Performance Manager and Unified Manager 7.2x due to error java.io.EOFException: unexpected end of stream:
