Downgrade a patch on RHEL/CentOS

To downgrade a patch that you have installed on your TeamForge site, run the patch installer from the directory corresponding to the patch.

1. Uninstall TeamForge CLI-add on.
   • cd /opt/collabnet/teamforge/add-ons/teamforge_cli_server
   • ./install --uninstall
   • yum erase teamforge_cli_server
2. Stop TeamForge.
   • /etc/init.d/collabnet stop all
   Note: In case of distributed setup, run the above command in the respective servers.
3. Run the downgrade command.
   Note:

   • When you downgrade, the backup of the site-options.conf file will be available in /opt/collabnet/teamforge-installer/8.1.0.0/conf directory.
   • You must downgrade TeamForge based on the services enabled in the server in case of distributed setup. For example, run the downgrade command yum downgrade teamforge-scm CN-collabnet-core CN-migration CN-runtime TeamForge-installer in case of "SCM on a separate server".
   • yum downgrade CN-collabnet-core CN-runtime CN-migration TeamForge-installer teamforge-database teamforge-etl teamforge-scm teamforge-codesearch ctf_clireports teamforge-binary teamforge-indexer teamforge_cli ctf_customization_installer
   • If you have git integration, add "teamforge-git" to the yum downgrade command as follows:
   • yum downgrade CN-collabnet-core CN-runtime CN-migration TeamForge-installer teamforge-database teamforge-etl teamforge-scm teamforge-codesearch teamforge-git ctf_clireports teamforge-binary teamforge-indexer teamforge_cli ctf_customization_installer
4. Install TeamForge and TeamForge CLI report packages by running the following command:
   • yum install teamforge-8.1.0.0-215 teamforge-app-8.1.0.0-215 ctf_clireports-2.4.0-168
5. Recreate the run time environment.
   • cd /opt/collabnet/teamforge-installer/8.1.0.0
   • ./install.sh -r -n -V -I
6. Start TeamForge.
   • /etc/init.d/collabnet start all
7. Run the following post-install.py script.
   • /opt/collabnet/teamforge/runtime/scripts/post-install.py
