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 IBM
Rational Insight or TRS consumer applications, such as
IBM Rational Engineering Lifecycle Manager, you must copy Derby files from your previous installation.
