Before you begin

  • You have applied the latest Talend Data Catalog 7.3 cumulative patch.
  • You have downloaded Talend Data Catalog 8.0.
  • You have downloaded the latest Talend Data Catalog 8.0 cumulative patch, if necessary.


  1. Stop Talend Data Catalog application server in the same way it was started, such as stopping the Windows services, stopping the desktop command Windows, or using the tomcat/bin/shutdown.
  2. Stop Talend Data Catalog database server as a new version of PostgreSQL server can be included as part of the upgrade.
  3. Back up your data including your database and data file directories.
    You can back up the PostgreSQL database instance by double-clicking backupDB.bat in TalendDataCatalog\postgresql\scripts.

    By default, the backup file is saved in the TalendDataCatalog\postgresql\backup folder.

    For more information, see https://www.postgresql.org/docs/.

  4. Back up your Talend Data Catalog software by copying the <TDC_HOME> directory to <TDC_HOME>.old.
  5. Create a new <TDC_HOME> installation directory.
  6. Install Talend Data Catalog 8.0 in the new directory for a clean installation of a new version.
    For more information, see Installing Talend Data Catalog.
  7. If necessary, apply the latest Talend Data Catalog 8.0 cumulative patch.
    Make sure you unzip the patch file in overwrite mode in the installation directory.
  8. To restore your data and software customizations and setup performed in Talend Data Catalog version 7.3, copy the appropriate files and directories from <TDC_HOME>.old to <TDC_HOME>.
    For more information, see Data storage location.
  9. Copy any new version of files from <TDC_HOME>\conf\Template into their matching directories in <TDC_HOME>\conf\ to integrate new or updated software features in your configuration.
    For example, ModelBridgeList.xml can contain new or updated bridges.

    For more information, see After upgrading Talend Data Catalog.

    If you have customized some files such as conf\resources\MM.properties, you must merge these customizations starting from the new version of that file copied from <TDC_HOME>\conf\Template.
  10. Reconfigure the database server using the Setup.bat file to upgrade it as the PostgreSQL software version has changed.

    The setup utility retrieves the existing PostgreSQL data from the old installation directory and migrates them to the new <TDC_HOME> directory, before starting the new PostgreSQL server.

    For more information about the installation and configuration procedures, see Installing Talend Data Catalog.

  11. Restart the Talend Data Catalog database server.
  12. Restart the Talend Data Catalog application server after which your first login as Administrator may prompt you for an upgrade of your database.
