Resolution

The user running the jboss-server-migration.sh needs to have access to the files under $JBOSS_HOME, so change the permissions on the configuration files mentioned and re-run the jboss-server-migration.sh.

Root Cause

Most likely, the permissions were changed and/or EAP was run as a different user than is used when the jboss-server-migration.sh is run, resulting in the user running jboss-server-migration.sh not having permission to the files in the source $JBOSS_HOME.
