Interactive MPP upgrade

After you upgrade the Primary EPM and all Auxiliary EPMs, upgrade the MPP.
On each server, launch the Experience Portal installation program and type the responses to the prompts. The procedure is similar to the interactive EPM software upgrade. For details, see Upgrading the MPP software interactively.
During the Interactive upgrade, you can make changes to the MPP configurations.
Tip:
In Experience Portal 7.0.1, the certificate generation code was enhanced to use a more secure hashing algorithm. Avaya recommends that you generate a SHA256 2048 bit server certificate (the new security certificate) to make the systems more secure.
Important:
Experience Portal provides the functionality to use an EPM 8.1 server with an already provisioned 7.2.3 MPP. However, it does not support adding an MPP that is at an earlier version to an EPM that is already upgraded to Experience Portal 8.1. If your system is configured to use more than one MPP, you can ensure that while you upgrade an MPP to 8.1, the other existing MPPs (of earlier versions) are functional. If the Experience Portal 8.1 EPM created a new server certificate during the upgrade, you must run the setup_vpms.php script on the MPP 7.2.3 server, trust the new certificate on the Change MPP page, and restart the MPP.
