Problem Description

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

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

[YYYY/MM/DD hh:mm:ss] [info] [100] Migrating index entry Job="Current" Path="Microsoft Exchange" Type="T" from v6 to v7
[YYYY/MM/DD hh:mm:ss] [cbs] [100] info,"Migrating index entry Job=\"Current\" Path=\"Microsoft Exchange\" Type=\"T\" from v6 to v7",0,0,0,,

[YYYY/MM/DD hh:mm:ss] [cbs] [100] info,Marking this v6 destination as index migrated to server ...,0,0,0,,

Index migration should only be performed once by the initial backup job performed after the upgrade (except if the initial backup job failed).
