Reinstalling the EPM and MPP software on a single server

If your site uses customized scripts, do the following to ensure you do not lose those scripts when the installation procedure writes over the scripts for the Database Backup utility:

Navigate to the backup directory located in $AVAYA_HOME by entering the cd $AVAYA_HOME/Support/Database/DBbackup command.
Copy all the files in this directory to a temporary directory.

Log on to Linux on the Experience Portal server with root privileges.

The reinstallation procedure is identical to the upgrade procedure because the installation script will find a previous version of the EPM on the server. The fact that the previous version is the same release as you want to install makes no difference to the installation script. You can reinstall the EPM software by running the aepinstall command. If you run the aepinstall command, you must do the following after installing the Experience Portal software:

Run the setup_vpms command to reauthorize the security certificate.
Reestablish the link between the MPP and the EPM by trusting the MPP's security certificate.

	Note:
	For more information about the aepinstall command, see Implementing Avaya Experience Portal on a single server.

If you copied your customized Database Backup utility scripts to a temporary location at the beginning of this procedure, copy your customized files back to the /var/lib/pgsql/DBbackup directory.
