If you have multiple Experience Portal systems, you may want to set up a shared external database so that you can log into the EPM for one system and:
Once you connect the Experience Portal system to the external database, that system stores all its report data in the external database from that point forward. The report data includes:
Contact Detail Records (CDRs)
Session Detail Records (SDRs)
Application Detail Records (ADRs)
Performance report records
Important:
You must back up the external database manually using your database administration tools. You cannot use the Avaya Experience Portal Database Backup utility to back up an external database.
