Migrate OnCommand performance manager data to unified manager ( Job remain in progress)

Recently, an OCPM (OnCommand performance manager) managed NetApp Cluster data was migrated to OCUM (OnCommand Unified Manager) v7.2P1.

The steps to migrate the cluster data was straight forward and the steps are mentioned here.

The trouble was that after the migration was initiated the job remained IN-PROGRESS for almost 2 weeks and there was no way to ascertain if the job was in progress.

A support case was raised with NetApp and a support bundle was generated. Upon analysis it was found that there was an events table that was too large. Here is a snippet from the logs:
