Backing Up the Database

Upgrades: All upgrades.

Environments: Development environment only.

Perform a full backup of the database, using the utilities specific to your database platform. This backup protects your repositories and environment.

It is a recommended practice that you back up your database at key stages of the upgrade:

• Before any upgrade activity is started
• After upgrading the Siebel Database Schema or Custom Database Schema (upgrep+upgphys)
• After the repository merge
