Problem Description

For MS Exchange DAG mail level backup set created by AhsayOBM version 6, after upgrading the client application to version 7.3.2.0 - 7.5.0.2, index migration is performed on every backup jobs.

The following informative messages are received in the Backup Job Logs during index migration:
