Currently, the Migration Guide only mentions the WildFly Server Migration tool briefly. As JBEAP-2791 explains, it will be our first and foremost supported way that our customers should use to upgrade servers from EAP 6 to EAP 7. The Migration Guide will have to describe its usage.

This of course depends on availability of the tool, which is currently unknown (at least to me).

When the documentation for the tool is ready, we have to update the Important note at the beginning of chapter 3.1. Management CLI Migration Operations.
