Preparing for upgrade

Before performing the upgrade of Remedy Single Sign-On to the latest version, you must first follow the preparation steps.

Before you begin

Review system requirements to make sure that all required hardware and software are available to upgrade Remedy SSO on a target server.

To prepare for the upgrade

1. Before you upgrade Remedy SSO, make sure that you have the required permissions to run the installer, and the required user permissions for the Remedy SSO database. For information about required permissions, see Installation permissions.
   
2. From the BMC Electronic Product Distribution (EPD) site, download the Remedy SSO upgrade files, unzip and save them on all the servers where you want to upgrade Remedy SSO. For information about how to download the installation files, see Downloading the installation files.
3. Make a backup copy of the Remedy SSO database. At a later time, if you need to roll back the upgrade, you will be able to reapply the old configuration.
   
4. If you have applied custom settings in the web.xml located in the < Remedy SSO Tomcat>\webapps\rsso\WEB-INF folder on the Remedy SSO server, create a backup of these settings.  

Where to go from here
