After JBEAP-3816 was fixed, chapter 5.18.5. Migrate Clustering HA Singleton of the Migration Guide contains wrong link to the documentation of HA singleton services.

Currently, the text in Migration Guide links to https://access.redhat.com/documentation/en/red-hat-jboss-enterprise-application-platform/version-7.0/development-guide/#clustered_ha_singleton_service and the link is called "Clustered HA Singleton Service".

The correct anchor is #ha_singleton_service and the chapter is called just "HA Singleton Service".
