The migration tool can't migrate the JBoss EAP 6.4.x to JBoss EAP 7.1 when the JBoss was installed from RPM and is using symbolic links in the JBOSS_HOME directory.

Below is the example of the JBoss installed from RPM using symbolic links:

The domain and standalone directories do not migrate after running the migration tool.
