To upgrade from Oracle Empirica Signal 9.1.0.x, 9.2.0.x, 9.2.1.x, or 9.2.2.x to 9.2.3, it is necessary to restore site-specific properties files.

1. In a command shell, navigate to the backup directory <INSTALL_DIR>/Signal_Install_old/Signal/WEB-INF/classes.
2. Copy the webvdme.properties file to the installation area. For example:
   $ cp webvdme.properties /u01/stage/Signal_Install/Signal/WEB-INF/classes
3. Update the webvdme.properties file in /u01/stage/Signal_Install/Signal/WEB-INF/classes:
   1. Update the Oracle Empirica Signal help URL content from /u01/stage/Signal_Install/Signal/WEB-INF/classes/template_webvdme.properties and, if custom help is configured, uncomment help.url:

      # Signal help URL
      # To override the default help URL, uncomment and change the major version and patchset version if available of the URL
      # e.g., help.url=https://docs.oracle.com/pls/topic/lookup?ctx=en/industries/health-sciences/empirica-signal/9.x/userguide&id=
      #help.url=https:/docs.oracle.com/pls/topic/lookup?ctx=en/industries/health-sciences/empirica-signal/
      <majorVersion.minor.Version.[patchsetVersion]>/userguide&id=

   2. Remove deprecated property oracleHelpCenter.url and related content.

      # Oracle Help Center URL for hosting help content
      # If the property or its value is not set, then help will default to the local help file
      oracle.HelpCenter.url=https://docs.oracle.com/health-sciences-empirica-signal-90./ESIUG

4. Copy the listener.properties file to the installation area. For example:

   $ cp listener.properties /u01/stage/Signal_Install/Signal/WEB-INF/classes

5. Copy the report_listener.properties file to the installation area. For example:

   $ cp report_listener.properties /u01/stage/Signal_Install/Signal/WEB-INF/classes

6. Copy the webvdme-fonts.properties file to the installation area. For example:

   iText.TABLE_WRITER_BASE_FONT_PATH=GoNotoCurrentJp.ttf 
   iText.CASE_SERIES_DETAIL_BASE_FONT_PATH=GoNotoCurrentJp.ttf 
   iText.TOPIC_WRITER_BASE_FONT_PATH=GoNotoCurrentJp.ttf

7. Copy the log4j2.xml file to the installation area, overwriting the existing file. For example:
   $ cp -f log4j2.xml /u01/stage/Signal_Install/Signal/WEB-INF/classes
8. If Oracle Empirica Signal is integrated with LDAP, copy the Oracle Empirica Signal file to the installation area. For example:

   $ cp ldap.properties /u01/stage/Signal_Install/Signal/WEB-INF/classes

9. In a command shell, navigate to the backup directory <INSTALL_DIR>/Signal_Install_old/TopicsService/WEB-INF/classes.

    $ cp webvdme.properties /u01/stage/Signal_Install/TopicsService/WEB-INF/classes
