There is no automated migration path for Fuse 7.0. A new installation must be performed, with configuration and other modified files copied across manually. Applications will need to be recompiled to align with the new versions provided. Use the Maven Bill of Materials (BOM) file to migrate Maven dependencies to the new versions and see also Component Details.

There is no automated migration path to Fuse 7.0 on EAP from previous version of Fuse on EAP. To migrate to Fuse 7.0 you will need to make a new installation of Fuse 7.0 on JBoss EAP. After a successful installation, any existing deployments will need to be re-deployed to the new system. For installation information please see Installation on JBoss EAP and for deployment information see Deployment in the Management Console.

For the list of features that have been deprecated or removed in Fuse 7.0, see Release Notes.

The console commands have been renamed in Apache Karaf 4.x and differ from what they are in 2.x. The purpose is to standardize the naming convention.

The following table lists the old commands and the new commands:

The JMX MBeans object names are renamed and the operations are dispatched in new MBeans.

The table below lists the old JMX MBeans object names and the respective new object names.

This section covers the changes in Karaf 2.x to Karaf 3.x.

The messaging subsystem on EAP 7.x uses Artemis instead of HornetQ. You need to migrate custom EAP CLI scripts that reference the old EAP 6.x messaging subsystem to Artemis. See, EAP migration guide [https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/7.1/html-single/migration_guide/index] for details.

The WildFly management port is changed to 9990. The old port number 9999 is no longer in use. For configurations that use the wildly-maven-plugin in the pom files, you must remove references to port 9999 as the plugin defaults to 9990.

The camel-restlet component has been removed from Fuse on EAP. The camel-restlet producers are supported, but the consumers working on the old EAP JBoss Web stack never worked. Considering that we support a number of alternative HTTP components, the camel-restlet component was removed from Fuse 7.

You should switch to an alternate HTTP consumer component such as undertow, http4, netty-http4, and so on.

The camel-cxf consumers are supported in Fuse 7.x. You can migrate to 'skinny' WAR deployments instead of deploying 'fat' camel WAR deployments or other workarounds for using CXF consumers in Fuse EAP 6.x.

You need to update the Maven POMs to reference to the latest BOM & Fuse and EAP artifact versions.

The purpose of a Maven Bill of Materials (BOM) file is to provide a curated set of Maven dependency versions that work well together, saving you from having to define versions individually for every Maven artifact.

The Fuse BOM for Apache Karaf offers the following advantages:

To incorporate a Maven BOM file into your Maven project, specify a dependencyManagement element in your project’s pom.xml file (or, possibly, in a parent POM file), as shown in the following example:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<project ...>
  ...
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

    <!-- configure the versions you want to use here -->
    <fuse.version>7.0.0.fuse-000191-redhat-1</fuse.version>
    <bom.version>7.0.0.fuse-000027-redhat-1</bom.version>

    <maven-compiler-plugin.version>3.3</maven-compiler-plugin.version>
    <maven-surefire-plugin.version>2.18.1</maven-surefire-plugin.version>
  </properties>

  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.jboss.redhat-fuse</groupId>
        <artifactId>fuse-karaf-bom</artifactId>
        <version>${bom.version}</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>
    </dependencies>
  </dependencyManagement>
  ...
</project>

After specifying the BOM using the dependency management mechanism, it becomes possible to add Maven dependencies to your POM without specifying the version of the artifact. For example, to add a dependency for the camel-velocity component, you would add the following XML fragment to the dependencies element in your POM:

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-velocity</artifactId>
</dependency>

Note how the version element is omitted from this dependency definition.

    <maven-compiler-plugin.version>3.3</maven-compiler-plugin.version>
    <maven-surefire-plugin.version>2.18.1</maven-surefire-plugin.version>
  </properties>

        <version>${bom.version}</version>
        <type>pom</type>

The Fuse BOM for Spring Boot offers the following advantages:

To incorporate a BOM file into your Maven project, specify a dependencyManagement element in your project’s pom.xml file (or, possibly, in a parent POM file), as shown in the following example:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<project ...>
  ...
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

    <!-- configure the versions you want to use here -->
    <bom.version>7.0.0.fuse-000027-redhat-1</bom.version>
    <spring-boot.version>1.5.13.RELEASE</spring-boot.version>

    <maven-compiler-plugin.version>3.3</maven-compiler-plugin.version>
    <maven-surefire-plugin.version>2.18.1</maven-surefire-plugin.version>
  </properties>

  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.jboss.redhat-fuse</groupId>
        <artifactId>fuse-springboot-bom</artifactId>
        <version>${bom.version}</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>
    </dependencies>
  </dependencyManagement>

</project>

After specifying the BOM using the dependency management mechanism, it becomes possible to add Maven dependencies to your POM without specifying the version of the artifact. For example, to add a dependency for the camel-hystrix component, you would add the following XML fragment to the dependencies element in your POM:

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-hystrix-starter</artifactId>
</dependency>

Note how the Camel artifact ID is specified with the -starter suffix — that is, you specify the Camel Hystrix component as camel-hystrix-starter, not as camel-hystrix. The Camel starter components are packaged in a way that is optimized for the Spring Boot environment.
