Upgrading DOORS and DWA

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