Understanding Overwrite or Create Server Group options
If you install a BMC Remedy Action request (AR) System server over an existing AR System server, you are prompted to upgrade, overwrite, or create a server group for the existing BMC Remedy AR System database.
If you select the Overwrite option, a new BMC Remedy AR System database is created, and you lose your existing data and structures. The server uses the database name and user name that it used for the previous installation.
If you plan to restore your BMC Remedy AR System data after installation, export your BMC Remedy AR System data and definitions before installation.

If you select the Server Group option for an AR System server, you tell the installation program that this AR System server will share an existing database with another AR System server.
