Before you begin

  • You have downloaded the latest Talend Data Catalog 7.1.2 cumulative patch.
  • You have downloaded Talend Data Catalog 7.3.
  • You have downloaded the latest Talend Data Catalog 7.3 cumulative patch.


  1. Apply the latest Talend Data Catalog 7.1.2 cumulative patch and make sure your Talend Data Catalog 7.1.2 is running fine.
    For more information, see Applying a patch manually.
  2. Make sure the regularly scheduled database maintenance has run successfully.
  3. Stop Talend Data Catalog database server and application server.
  4. 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/.
  5. Back up your Talend Data Catalog software by renaming the <TDC_HOME> directory as <TDC_HOME>.old.
  6. Install Talend Data Catalog 7.3 in a new <TDC_HOME> directory.
  7. Apply the latest Talend Data Catalog 7.3 cumulative patch.
  8. Restore your data and setup customizations performed in Talend Data Catalog version 7.1.2 by copying the appropriate files and directories from <TDC_HOME>.old to <TDC_HOME>.
    For more information, see Before upgrading.
    Note: 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.
  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.
    Note: Any upgrade must also be followed by a re-import of models, and re-build of the configurations to take advantage of the new capabilities.
    Note: Upgrading to a new version may also have version specific issues or recommendations. For more information, see Version specific upgrade issues and recommendations.


You are now ready to 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 on the new directory.
