The text in the Migration Guide currently states it will be the preferred method of migration when the tool goes final. It is not supported in the pre-release version.

When it goes GA, I need to modify the following topics:

docs/topics/migration-tool-server-migration-tool.adoc
docs/topics/migrate-management-cli-migration-operations.adoc
docs/topics/migrate-server-configuration-options.adoc

I also need to use the document attribute for the tool name in this topic:

docs/topics/migrate-messaging-data.adoc
