Migrating to Talend Data Stewardship 7.3.x with an embedded MongoDB

Before you begin

If you have installed and used Talend Dictionary Service to create custom semantic types or update the predefined ones, you must migrate Talend Dictionary Service before migrating Talend Data Stewardship. See Migrating to Talend Dictionary Service 7.3.x.

Download Talend Data Stewardship 7.3.x.

Upgrade Talend Administration Center. For more information, see Upgrading Talend Administration Center.

Procedure

  1. Stop your current Talend Data Stewardship instance but keep MongoDB running.
  2. Back up the MongoDB instance used for the previous version of Talend Data Stewardship using the following command.
    For Linux:
    <mongo_path>/bin
./mongodump -h <source_mongodb_host>:<source_mongo_port> -u <mongo_tds_username> -p <mongo_tds_password> -d <mongo_tds_database> -o <backup_location>
    For Windows:
    <mongo_path>/bin>mongodump -h <source_mongodb_host>:<source_mongo_port> -u <mongo_tds_username> -p <mongo_tds_password> -d <mongo_tds_database> -o <backup_location>
    The default value for the embedded MongoDB properties are the following:
    Property Value
    mongodb.host localhost
    mongodb.port 27017
    mongodb.database tds
    mongodb.user tds-user
    mongodb.password duser
  3. Stop the MongoDB instance from the previous version of Talend Data Stewardship.
    Information noteNote: For Windows users, you must uninstall the current MongoDB before you install Talend Data Stewardship 7.3.x.
  4. Install Talend Data Stewardship 7.3.x and select the embedded MongoDB option. Do not start Talend Data Stewardship, but start MongoDB.
  5. Delete the database
    1. Open a mongo shell as a Talend Data Stewardship database user and execute the following commands.
      For Linux:
      cd <install_dir>/mongodb/bin
./mongo tds -u tds-user -p duser --port 27017
      For Windows: 
      <install_dir>\mongodb\bin>mongo tds -u tds-user -p duser --port 27017
    2. Switch to the Talend Data Stewardship database: use tds
    3. Drop the database: db.runCommand( { dropDatabase: 1 } )
    4. Exit mongo shell: exit
  6. Restore the MongoDB backup on the new 7.3.x MongoDB instance by using the following command.
    For Linux:
    <mongo_path>/bin
./mongorestore -h <mongo_host>:<mongo_port> -u <mongo_tds_username> -p <mongo_tds_password> -d <mongo_tds_database> <backup_location>
    For Windows: 
    <mongo_path>/bin>mongorestore -h <mongo_host>:<mongo_port> -u <mongo_tds_username> -p <mongo_tds_password> -d <mongo_tds_database> <backup_location>
  7. If you have customized the <Data_Stewardship_Path>/conf/data-stewardship.properties file in the previous version, you can copy the values from the old configuration file and add them to the new version.
  8. Delete the <install_dir>/tds/apache-tomcat/data folder from your Talend Data Stewardship 7.3.x installation.
  9. Start Talend Data Stewardship 7.3.x.
  10. Republish semantic types using Talend Dictionary Service API to migrate indexes to Lucene 8.
    For more information, see Talend Dictionary Service Administration Guide.
