Upgrading Rational DOORS and Rational DOORS Web Access
Beginning with version 9.6.1, the IBM® Rational® DOORS® client is only available as a 64-bit client. To upgrade you must manually remove your existing Rational DOORS client by uninstalling your existing version. To remove the interoperation server on Linux, delete the existing files. If the Rational DOORS database server or Rational DOORS Web Access is already installed on your system, the installers can upgrade your system to a new release; you simply install the new version. However, if Rational DOORS Web Access integrates with Jazz® Reporting Service or TRS consumer applications, such as IBM Rational Engineering Lifecycle Manager, you must copy Derby files from your previous installation.
