   • /etc/default/gws
3. Remove the following service initialization scripts from the host:
   • /etc/init.d/gws
   • /etc/default/gws
4. Deploy the new version of Web Services and Applications.
5. Copy the following configuration files from the configuration folder in your previous installation into the config folder in the home directory of the new installation:
   • application.yaml
   • elasticsearch.yml
   • hystrix.properties
   • logback.xml
   • statistics.yaml
6. On the Red Hat Linux 6 platform, open the /etc/default/gws file and update the following environment variables to values appropriate for your Web Services node:
   • GWS_HOST: This value must match the host value defined in jetty section of the application.yaml file.
   • GWS_PORT: This value must match port value that you will define later in jetty section of the application.yaml file.
7. Update the application.yaml file with the new path to the logback.xml file.
