Procedure
Stop your instance of the previous version of Talend Dictionary Service but keep MongoDB
running.
Backup your MongoDB, while it is still running, using the following command:
mongodump -h <source_mongodb_host>:<source_mongo_port> -d
<source_database> -u <source_mongodb_user> -p
<source_mongodb_password> -o <dump_output>
Talend Dictionary Service
7.3.x uses the 3.4.2 version of MongoDB.
Restore MongoDB, open a command prompt window and execute the following
command: <mongo_path>/bin/mongorestore -h
<mongo_host>:<mongo_port> -u <mongo_dq_username> -p
<mongo_dq_password> -d <mongo_dq_database>
<backup_location>
Install Talend Dictionary Service 7.3.x with the external MongoDB, and configure it with the
same settings as your instance of the previous version of Talend Dictionary Service, especially the links to
your Talend Administration Center and point to
MongoDB 3.4.2.
For more information about the Talend Dictionary Service installation and
configuration procedures, see the Talend Installation Guide.
If you have performed any custom configuration to the previous version of the
<Tomcat>/conf/data-quality.properties file, update the
7.3.x version of the file by coping the values from the old configuration file.
Start Talend Dictionary Service 7.3.x by launching, in order:
Apache Zookeeper
Apache Kafka
Apache Tomcat (Talend Administration Center server and Talend Identity and Access Management server)
MongoDB

You are now ready to use Talend Dictionary Service 7.3.x.
