[1] The full content of the migrate subsystem sections should match the one at  https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/7.4/html-single/using_the_jboss_server_migration_tool/index#migrate_the_jacorb_subsystem , just changing the 3 attributes found in linked sources (name of the subsystem which is migrated, name of the extension of the subsystem which is migrated, name of the replacement subsystem)

[2] Not sure if this is a new section, if there is already a section about updating jgroups then replace it with this one 

The new content should be placed right after the section wrt migrating Referenced Paths.
