Upgrade to MarkLogic Data Hub 5.1

The notes and steps in this tab are for the following upgrade paths:

• DHF 4.3 » 5.1

Procedure

1. In your project root directory, create a build.gradle file with the Grade Properties plugin setting and the Data Hub plugin setting.

   Copy the following to your build.gradle file and replace the com.marklogic.ml-data-hub version number with the Data Hub version that you are using.

      plugins {
         // Gradle Properties plugin
         id 'net.saliman.properties' version '1.4.6'
   
         // Data Hub plugin
         id 'com.marklogic.ml-data-hub' version '5.1.0'
     }
   

   net.saliman.properties	Gradle Properties plugin	Allows you to create different environments for your Gradle deployment and set up a gradle-{env}.properties file, where {env} is the environment name. When running a Gradle task, you can specify the target environment with the environmentName option. For more information, see https://github.com/stevesaliman/gradle-properties-plugin.
   com.marklogic.ml-data-hub	Data Hub plugin	Extends the ml-gradle plugin with Data Hub-specific commands.

2. At your project root, run the Gradle task hubUpdate.

   Running the hubUpdate task with the -i option (info mode) displays specifically what the task does, including configuration settings that changed.

   Unix systemsWindows
   ./gradlew hubUpdate -igradlew.bat hubUpdate -i

   hubUpdate automatically moves the following artifacts to the new project.

   From old project	To Data Hub 5.1.0 project
   your-project-root/plugins/entities/entity1/entity1.entity.json ... your-project-root/plugins/entities/entityN/entityN.entity.json The input and harmonize folders remain in the same plugins/entities/entity* folders.	your-project-root/entities/entity1.entity.json ... your-project-root/entities/entityN.entity.json
   your-project-root/plugins/mappings (the entire directory)	your-project-root/mappings

3. Update your gradle.properties file to change the value of mlDHFVersion to 5.1.0.

   mlDHFVersion=5.1.0

4. Run the Gradle task mlRedeploy.
   Unix systemsWindows
   ./gradlew mlRedeploy -igradlew.bat mlRedeploy -i
   Tip: You can use Gradle's -i option to enable info-level logging.
5. (Optional) Migrate your 4.3 flows to 5.x steps.
