Comment migration working? (D5 --> D7) View displaying comments not
Things I learned today, yes it took me all day, and I learned a lot. Like to test your assumptions. Test them early and verify the problem you're trying to solve in fact is in the place you are looking.

My debacle outlined above was completely separate from all the comment tables. The maddening part, was I narrowed it down to the comment bodies not appearing (or so I thought) because I was using a view to display the author's name, followed by the comment. Where this view pulled the author name from was the comment table, where the author's name wasn't was in the users table, I hadn't run the user migration in a couple weeks &amp; enough users had joined &amp; commented that, well, you get the picture. 

Also contributing to the madness was the lack of information in the error messages, I kept getting malformed entity exceptions, which is probably because I was using views to display the comments.

Something else I noticed, that a comment's initial changed time is a few seconds before it's created time, not sure that's a bug, but definitely a quirk.
