(v23) Migrate Connectors for Other Versions

Migrate Connectors for Other Versions

Zoomdata 4.1 introduced a new microservice registration model for connectors. The new model is not fully compatible with earlier versions of Zoomdata. Special migration steps must be performed if you want to use a:

• Use a 4.1 (or Later) Connector With Zoomdata 4.0 (or Earlier)
• Migrate Connectors for Other Versions

Zoomdata 3.2 to 4.0 connectors are fully compatible with Zoomdata 4.1 (or later) and Composer 5.7 (or later).

Use a 4.1 (or Later) Connector With Zoomdata 4.0 (or Earlier)

Before you can use a Zoomdata 4.1 (or later) or Composer 5.7 (or later) connector with Zoomdata 4.0 (or earlier) installation, you must complete the following migration steps.

1. Contact Technical Support to obtain the code for the newer connector you want to use.

2. Install the newer connector supplied by Technical Support.

   $ sudo yum install <composer-edc-connector>

3. Make sure you have a copy of the connector's property file in /etc/zoomdata. The supported property file names are listed in Connector Properties and Property Files. If the property file does not exist in /etc/zoomdata, copy the file from /opt/zoomdata/conf. If the property file does not exist in /opt/zoomdata/conf, then just create the file (using the supported name) in the /etc/zoomdata folder.

4. Edit the connector's property file in the /etc/zoomdata folder and change the value of the spring.application.name property to edc.

   ... spring.application.name=edc ...

5. Save the property file and start or restart the appropriate connector microservice.

   $ sudo systemctl start <connector-service-name>

   See Start Composer Microservices and Restart Composer Microservices for more information. Microservice names are listed in Composer  Microservice Name Reference.

The newer connector will now work with your earlier version of Zoomdata.
