Hi, Gregg,
I’ll try to prepare short guide, but main steps would be:
1. re-assigning logo, for that you need to have Jetpack or Site Logo plugin active: http://mtomas.com/389/tiny-forge-framework-child-themes-comprehensive-guide#Header-and-logo-configuration-options
2. If you had any custom CSS and used rem values, you would have to replace those with new ones because theme migrated from 14px rem base to 16px, but style.css includes most of the values, so it’s just find-and-replace job in the text editor.
3. You might need to adjust width and height of certain elements if you had custom CSS styles, because theme now is using new box model.
If I will come up with other possible steps, I’ll append this list.
First I would just try to activate it and see how it looks, perhaps everything will be in a good shape 🙂
I gathered most migration tips here:

Let me know if you will face anything that is not included in the migration guide.
