Cool! I am looking to expand it for all the various project settings as a
complete migration guide.

The idea is to use BBv2 options in variants such as <warnings>off, so these
are converted appropriately to the correct flags for a toolset. However, you
might want to try:

variant crazy : profile :

Now we are getting into the territory of the BBv2 user manual. The idea of
the migration guide is to give VC/VS IDE users a way of getting up to speed
with the BJam/BBv2 terminology and the settings available so they have a
quick reference on how some IDE-related thing is done in BBv2. It is not
meant as a replacement for the BBv2 user manual (which should contain
information on extending variants), but should rather complement it :).

You should be able to do:

exe optimised : main.cpp
<cxxflags>/GL <linkflags>/LTGC

This is what the migration guide was meaning by the
<cxxflags>/GL <linkflags>/LTGC
line. I should really make this clearer in the introduction section.
