Upgrading with overlays already present
This topic describes the basic steps required to upgrade BMC Remedy AR System, BMC Atrium Core, and other BMC products with overlays already present. This is a four-stage upgrade if you have previously installed BMC Remedy AR System 7.6.04 and have already implemented overlays.
- If you are upgrading from pre-7.6.04 versions of BMC Remedy AR System to version 8.1, first take a backup of the customizations (system forms of Approval Server, Assignment Engine, Email Engine, and Flashboards), upgrade to version 8.1, and then manually add the customizations for version 8.1.
- Before beginning your upgrade, review the Planning topics. To understand the difference between the two upgrade paths, see Planning to upgrade BMC Remedy AR System.
- To upgrade the AR System server in a directory that already has the ar.conf file, select the Upgrade option, else select the Install option. If you select the Upgrade option, the installation program skips some of the server installation screens and refers to the configuration values in the ar.conf file.
Prepare to upgrade

Review the requirements for your computer platform:
Prepare your database before you start the upgrade.
Back up the BMC Remedy AR System database. This enables you to restore BMC Remedy AR System to its pre-installation state if you encounter problems.
