  1. Stop Appian. See Starting and Stopping Appian for detailed instructions:
    1. Shut down the application server.
    2. Shut down the search server.
    3. Shutdown all Appian Engines, ensuring that the engines are checkpointed upon shutdown.
  2. Back up your existing Appian instance. See Backing Up Your Existing Appian Instance for instructions.
  3. Unzip the contents of the 17.2.0.0_Hotfix_Package_R.zip archive into your <APPIAN_HOME> directory.
  4. Run the deleteFiles script (deleteFiles.bat on Windows, deleteFiles.sh on Linux) that is now located in your <APPIAN_HOME> directory.

  6. If it exists and is empty, delete the directory: <APPIAN_HOME>/search-server/plugins/appian-elasticsearch-auth
  7. Delete the deleteFiles script and updates.zip.
  8. If you are using a Web server, copy the content of <APPIAN_HOME>/ear/suite.ear/web.war to the folder where the Web server is getting the static resources. See Copy Static Resources to the Web Server for more information.

    • If you are running WebLogic, delete the <WEBLOGIC_HOME>/<project_name>/domains/<domain_name>/config/deployments/<suite.ear> and <WEBLOGIC_HOME>/<project_name>/domains/<domain_name>/servers/AdminServer/tmp/_WL_user/<suite> directories to clear the cache when re-deploying the application.
  10. If you are using WebLogic:
    • Delete the existing suite.ear from WebLogic.
    • Deploy the Appian EAR.
      • From the WebLogic Administration Console, on the Deployments screen, click Install.
      • Select suite.ear (<APPIAN_HOME>/ear/suite.ear) and click Next.
