Upgrade Process Intelligence

If you have installed a previous version of Process Intelligence, you can upgrade to a later version and your databases and previous settings will be maintained.

Upgrade is only possible within Red Hat Enterprise Linux 7 versions. Under Red Hat Enterprise Linux 8 a new installation is required since previous versions do not support this operating system. However, it is possible to connect a remote database used in the previous Process Intelligence version by connecting to it during the installation process.

To update your Process Intelligence installation to the latest version:

  1. If you are using a local database, back it up along with the Storage folder in the installation directory. For more details, see Back up and restore the PostgreSQL databases.
  2. Run the Process Intelligence installation as described in Install Process Intelligence and follow the instructions in the installation wizard.
  3. When prompted to Import existing Timeline installation, select opt/Timeline or custom path depending on where the application is already installed.

  4. Select the PostgreSQL location when prompted Do you want ABBYY Timeline to use a local PostgreSQL instance or connect to a remote database?

    • When upgrading within Red Hat Enterprise Linux 7, database settings from any location are maintained.

    • Red Hat Enterprise Linux 8 requires a new installation. To work with existing data, you need to have a configured remote database from the previous Process Intelligence version and connect to it during the installation. If you choose the local instance option, a new database will be created.

  5. If you plan to configure HTTPS with SSL (recommended), specify the HTTPS port when prompted.

  6. If you plan to use an existing database, specify the existing values for connecting to it when prompted during installation.

    If using a local database, make sure that the correct values are entered. Incorrect user credentials will cause a new database creation.

  7. Complete the Process Intelligence installation.

  8. After the installation process is complete, configure HTTPS with SSL if necessary.

    During the installation process the ssl.conf.tpl file is copied to the $TIMELINE_INSTALLATION_DIR/nginx folder. This file stores the SSL configuration settings. To set up SSL locate the $TIMELINE_INSTALLATION_DIR/nginx folder and do one of the following:

    • Rename the ssl.conf.tpl file to ssl.conf.

    • Alternatively, merge the ssl.conf.tpl file with ssl.conf. Use this method if you made any changes to the ssl.conf file for a previous version of Process Intelligence.

  9. Perform an installation health check.
