database migration in 8.3.0: missing person

[Marcus Winston]

I did see that online doc, and followed it. What is confusing to me is 
whether the faces data is, or is not, "migrate-able". That is, when 
moving to MySQL Server, is all my previous face information essentially 
thrown away? When I read "all other databases have to be rebuilt as 
post-processing...", I'm not sure exactly what that means.

The Core database seems to have included all the face information, 
except for one person (one face). Rebuilding the faces database did not 
change that. Hence, I'm a little confused.
