Upgrading Rational DOORS and Rational DOORS Web Access
If IBM Rational DOORS is
already installed on your system, the Rational DOORS installers
can upgrade your system to version 9.5 or later. To upgrade IBM Rational DOORS Web
Access, you simply install the new version. However, if Rational DOORS Web
Access integrates with IBM Rational Insight or TRS consumer
applications, such as IBM Rational Engineering Lifecycle Manager,
you must copy Derby files from your previous installation.
