Book: Migration Guide, revision 430ed5b9852c73719cf48bc9627e4f65b0282af0
Section: 7.5.1. Migrate a Simple SSL Configuration to Elytron

There are two commands in step 4. The commands fail because they have to run in one batch.

There is missing alias-filter="server" attribute in key-manager element in the resulting XML of elytron subsystem (see step 2).

Legacy security realm (element) is not in legacy security subsystem (element). The beginning of the section should be reworded.

Links to security guides should be provided (referencing more information).
