Procedure

1. Open the pom.xml file of the project and remove the <version> tag from any dependencies under the following groups:

   • org.kie
   • org.drools
   • org.jbpm
   • org.optaplanner

2. Add the following dependency under the <dependencies> tag within the <dependencyManagement> section:

   <dependency>
     <groupId>org.jboss.bom</groupId>
     <artifactId>rhpam-platform-bom</artifactId>
     <version>${rhpam.version}</version>
     <scope>import</scope>
     <type>pom</type>
   </dependency>

   The ${rhpam.version} is the version of the org.jboss.bom:rhpam-platform-bom artifact in the Maven repository for Red Hat Process Automation Manager 7.0. You can view the version of the artifact by entering the repository and navigating to the maven-repository/org/jboss/bom/rhpam/rhpam-platform-bom directory. The name of the only sub-directory in this directory is the version. For example: 7.0.0.GA-redhat-1.

3. If your code uses any Drools CDI annotations (@KReleaseId , @KContainer, @KBase, @KSession), also add the following dependency:

   <dependency>
     <groupId>org.drools</groupId>
     <artifactId>drools-cdi</artifactId>
   </dependency>

   This dependency is necessary because the CDI extension for processing the annotations is now defined using a separate module. Without this dependency, the annotations do not work.

4. Replace the legacy jbpm-workitems dependency (if applicable) with one or more of the new dependencies. The new dependencies that you choose depend on the work items that your code uses.

   Legacy jbpm-workitems dependency:

   <dependency>
     <groupId>org.jbpm</groupId>
     <artifactId>jbpm-workitems</artifactId>
   </dependency>

   New jbpm-workitems dependency options:

   <dependency>
     <groupId>org.jbpm</groupId>
     <artifactId>jbpm-workitems-core</artifactId>
   </dependency>
   <dependency>
     <groupId>org.jbpm</groupId>
     <artifactId>jbpm-workitems-bpmn2</artifactId>
   </dependency>
   <dependency>
     <groupId>org.jbpm</groupId>
     <artifactId>jbpm-workitems-email</artifactId>
   </dependency>
   <dependency>
     <groupId>org.jbpm</groupId>
     <artifactId>jbpm-workitems-jms</artifactId>
   </dependency>
   <dependency>
     <groupId>org.jbpm</groupId>
     <artifactId>jbpm-workitems-rest</artifactId>
   </dependency>
   <dependency>
     <groupId>org.jbpm</groupId>
     <artifactId>jbpm-workitems-webservice</artifactId>
   </dependency>

5. Replace the legacy org.guvnor dependency (if applicable) with the new org.uberfire dependency.

   Legacy org.guvnor dependency:

   <dependency>
     <groupId>org.guvnor</groupId>
     <artifactId>guvnor-rest-client</artifactId>
   </dependency>

   New org.uberfire dependency:

   <dependency>
     <groupId>org.uberfire</groupId>
     <artifactId>uberfire-rest-client</artifactId>
   </dependency>

6. Replace the legacy org.kie.remote dependency (if applicable) with the new org.kie.server dependency.

   Legacy org.kie.remote dependency:

   <dependency>
     <groupId>org.kie.remote</groupId>
     <artifactId>kie-remote-client</artifactId>
   </dependency>

   New org.kie.server dependency:

   <dependency>
     <groupId>org.kie.server</groupId>
     <artifactId>kie-server-client</artifactId>
   </dependency>

   This dependency is necessary because Business Central no longer has execution server capabilities nor API endpoints related to the execution server.

7. Update the version of the project artifact and save the pom.xml file.

Procedure

1. Navigate to the extracted rhpam-7.0.0-add-ons folder in your temporary directory and extract the rhpam-7.0-migration-tool.zip sub-folder (if not extracted already).
2. Navigate to the extracted rhpam-7.0-migration-tool folder and open the upgrade-scripts folder. This folder contains database upgrade scripts that are required for applying changes to the database model made in Red Hat Process Automation Manager 7.0.
3. Log on to the Red Hat JBoss BPM Suite 6.4 database to be used with Red Hat Process Automation Manager 7.0 and run the relevant Red Hat Process Automation Manager 7.0 upgrade script, according to the supported database type. This prepares the database for Red Hat Process Automation Manager 7.0.
4. If you use Quartz as your scheduling service, additionally run the quartz-upgrade.sql script provided in the relevant database folder within the upgrade-scripts folder. This script updates your Quartz version to 2.2.3 in compliance with Red Hat Process Automation Manager 7.0 requirements.

Procedure

1. Rebuild each Java project using a regular Maven build.

   $ mvn clean install

2. Review all project data in each build to confirm successful migration.

   If you encounter build errors, verify that the project dependencies have been updated correctly. To review other product changes that may have impacted your Java project, see Chapter 6, Other migration considerations.
