Upgrading frevvo 

Please read the following upgrade steps prior to starting the migration.

Prepare for the upgrade

1. Please read and understand the Migration Considerations that may require your action before beginning.
2. Install OpenJDK (11.x) before beginning.

3. If upgrading from a version prior to v10.1, install Chrome on that same server as your frevvo installation. This is required for PDF Snapshot generation to work in your v11 installation.

   PDF Snapshot Generator: Install Chrome/Chromium

   A stable version of chrome or chromium browser needs to be installed on same server where frevvo is installed. First, check to see if Chrome is already installed. If not, use one of the following links to install Chrome or a Chromium browser.

   • Chrome
   • Chromium
   • Chromium Edge

   The snapshot generator looks for the chrome browser at the following paths. If found, it launches the browser.

   • /usr/bin/chromium

   • /usr/bin/chromium-browser

   • /usr/bin/google-chrome-stable

   • /usr/bin/google-chrome

   • /Applications/Chromium.app/Contents/MacOS/Chromium

   • /Applications/Google Chrome.app/Contents/MacOS/Google Chrome

   • /Applications/Google Chrome Canary.app/Contents/MacOS/Google Chrome Canary

   • C:/Program Files (x86)/Google/Chrome/Application/chrome.exe

   If the browser is not installed at any of these paths then set the CHROME_PATH environment variable to point to the correct path of the browser binary or set frevvo.chrome.path property in frevvo-config.properties file.

   Windows Os:

   • Open the Start Search, type in “env”, and choose “Edit the system environment variables”

   • Click the “Environment Variables…” button

   • Click the "New..." button in the "System Variables" section

   • Set the variable name to "CHROME_PATH" and the value to <path to chromium browser exe>
     

   MacOs/Linux

   • Set the CHROME_PATH environment variable in system profile files (/etc/profile, ~/.bash_profile, ~/.bashrc)
     export CHROME_PATH=/opt/bin/chromium

1. Stop frevvo with one of the methods listed below:

   1. Execute <frevvo-home>\stop-frevvo.[bat,sh]

   2. Stop the Insight Server by closing the window or if you are using the tomcat bundle by typing these commands in the <frevvo-home>\solr directory of your existing installation.
      
      bin\solr.cmd stop -all
      
      

   3. Stop frevvo and the Insight Server through the Computer Management Services console if they are running as Window's services.

2. Back up the forms database from your current frevvo installation.

3. Back up the current frevvo server's installation directory so that you have a copy of all custom configuration parameters.

4. Request a v11 license if you are upgrading from a frevvo version prior to v11.0.x.

Oracle DB Permission

Customers using Oracle DB should grand the following permission before upgrading.

GRANT EXECUTE ON SYS.DBMS_CRYPTO TO <frevvo user>;

If you do not do this, you may see an error like "liquibase.exception.DatabaseException: ORA-00904: "DBMS_CRYPTO"."HASH": invalid identifier" in the log file while upgrading, and the upgrade will fail.

Install Upgraded Version

1. Download the latest v11.0.x software. The download is a zip file. Extract the contents to any folder of your choice. This folder will be referred to as <frevvo-home> (note that the zip already contains a top-level frevvo folder).
2. Install a JDBC Driver.
3. Ensure that Chrome or a Chromium browser is installed on the same server as the frevvo installation for PDF Snapshot generation. See the related Installation Task for details.
4. If you increased Memory Settings in your previous installation, make those changes to the appropriate files in the new installation. Refer to Hardware and Memory Requirements for the details.
5. Navigate to the server.xml file in the <frevvo-home>\tomcat\conf directory of your v11.0.x installation

Configure the Database and Email

1. Select your database type

2. Refer to the Configure the Connection URL topic to point to your current frevvo database. If you are using SQL Server, remember to add the sendStringParametersAsUnicode property with a value of false to your database connection URL if it is not already there.

3. Configure Email
4. If you made changes to the Default Port in previous releases, make those changes again in the v11.0.x server.xml file.  
5. Configure SSL for tomcat if it was configured in prior version of frevvo. 
6. Save the changes to the server.xml file. 

Copy Properties

See Installation Tasks for commonly used properties. Read the Detailed Release Notes to be sure that all properties you are using are valid in the upgraded version.

1. Edit the frevvo-config.properties file in your prior version. This file is usually located in the<frevvo home>/tomcat/conf directory.
2. Copy the properties you added or changed.
3. Edit the frevvo-config.properties file in the upgraded version, and paste the properties you copied from your prior version. 
4. Save the frevvo-config.properties file.

Start the Insight Server

Follow the steps to start the Insight server BEFORE starting frevvo.

Windows:

1. Open a command prompt. Navigate to <frevvo-home>\solr. Type bin\solr.cmd start to run the Insight server in the background, listening on the default port 8983.
   
   
   

2. You will see this message:
   
   
   
   

   If you close the Insight server (Solr) startup window, the server will stop running. Leave the window open or see these instructions to remove existing services and set up frevvo and the Insight Server to run as Windows services:

3. Browse http://<your server:port>/ solr to verify the Insight server is running. The <server:port> default values are localhost:8983. Change localhost to the server name and 8983 to the port the Insight server is running on if they are different than the defaults. Do not include the angle brackets <>. You will see the Insight server (Solr) dashboard with the current status.

Linux:

1. Ensure that the scripts are executable: chmod 755 <frevvo-home>/tomcat/bin/*.sh
2. Navigate to <frevvo-home>/solr/bin. Run this command to make the solr startup file executable:
   chmod +x solr
3. Navigate back to the solr directory. 
   cd ..     
4. Start the Insight server by typing: bin/solr start - this starts the Insight server in the background.
5. Browse http:<your server:port>/solr to verify the Insight server is running. The <server:port> default values are localhost:8983. Change localhost to the server name and 8983 to the port the Insight server is running on if they are different than the defaults. Do not include the angle brackets <>. You will see the Insight server (Solr) dashboard with the current status.

Start frevvo

Start the frevvo v10.1.x server by running the start-frevvo.bat or start-frevvo.sh files (depends on your Operating system) in the <frevvo-home>\frevvo directory. Then follow these instructions to login and enter your upgrade license key.

If you are running frevvo and the Insight Server (Solr) as Windows services, you must delete the existing services then reinstall them for the services to run properly.

1. Follow these steps to delete the existing Insight Server service for Windows Vista, 7, 8 or 10 operating systems:
   1. Login as an administrator.
   2. Verify the Insight Server service name by double clicking it in the Windows Services list

   3. Type this command: If your service name has spaces in it, use quotes around the service name.

      sc delete <ServiceName>

   4. The message "DeleteService SUCCESS' will display when successful.

   5. Remove the frevvo service by running the <frevvo-home>\Remove-Service batch file. 

2. Perform these steps to reinstall the Insight Server and frevvo services.

Connectors

Ensure you upgrade to the supported version of the connectors for your upgraded version of frevvo. Version information can be found at the links below.

• If you are using the frevvo Database Connector, you must reinstall and configure it again for the v11.0.x installation.
• If you are using the Google connector you must reinstall and configure them for the v11.0.x installation.
• If you are using the frevvo Filesystem Connector, you must reinstall and configure it again for the v11.0.x installation.
• If you are using the frevvo SharePoint Connector you must reinstall and configure it again for the v11.0.x installation.
• If you are integrating with IIS, review these updated steps to configure Tomcat. 

sameSiteCookies Attribute

Recent browser versions (especially Chrome v80+), by default, allow cookies to be sent only with top-level navigation and GET request initiated by third-party websites. When you need to expose cookies to a third party site, such as using the SAML security manager or embedding in an iframe, you need to use https (Chrome only) and explicitly set the samesite attribute of the cookie to "none". frevvo includes a tomcat version that allows configuring the cookie processor with this attribute. This documentation provides more information and details across browsers.

For third party access, you must use https and update the provided tomcat/conf/context.xml CookieProcessor element to add the sameSiteCookies attribute.

<CookieProcessor className="org.apache.tomcat.util.http.LegacyCookieProcessor" allowEqualsInValue="true" sameSiteCookies="none"/>

On premise customers who do not want to make these updates need to turn on the legacy behavior in the chrome browser. Please see this Chrome documentation for details.
