Chapter 3. Tools to Assist in Migration

3.1. Use RHAMT to Analyze Applications for Migration

Red Hat Application Migration Toolkit (RHAMT) is an extensible and customizable rule-based set of tools that helps simplify migration of Java applications. It analyzes the APIs, technologies, and architectures used by the applications you plan to migrate and provides detailed migration reports for each application. These reports provide the following information.

  • Detailed explanations of the migration changes needed.
  • Whether the reported change is mandatory or optional.
  • Whether the reported change is complex or trivial.
  • Links to the code requiring the migration change.
  • Hints and links to information about how to make the required changes.
  • An estimate of the level of effort for each migration issue found and the total estimated effort to migrate the application.

You can use RHAMT to analyze the code and architecture of your JBoss EAP 6 applications before you migrate them to JBoss EAP 7. The RHAMT rule set for migration from JBoss EAP 6 to JBoss EAP 7 reports on XML descriptors and specific application code and parameters that need to be replaced by an alternative configuration when migrating to JBoss EAP 7.

For more information about how to use Red Hat Application Migration Toolkit to analyze your JBoss EAP 6 applications, see the Red Hat Application Migration Toolkit Getting Started Guide.

3.2. Use the JBoss Server Migration Tool to Migrate Server Configurations

You can use the JBoss Server Migration Tool to update your configuration to include the new features and settings in JBoss EAP 7 while keeping your existing configuration.

The JBoss Server Migration Tool reads your existing JBoss EAP 6 server configuration file and adds configurations for the new subsystems, updates existing subsystem configurations with new features, and removes obsolete subsystem configurations.

The binary distribution of JBoss Server Migration Tool 1.0.0.Final is available for download from https://github.com/wildfly/wildfly-server-migration/releases. This version supports the migration of standalone servers and managed domains from JBoss EAP 6.4 to JBoss EAP 7.0. For general information about how to run the tool, see the JBoss Server Migration Tool User Guide.

Note

The JBoss Server Migration Tool is not supported in JBoss EAP 7.0.
