Nice work! this looks great. I have some minor comments:
Can we remove the Having trouble? Let us take over text + link at the bottom of the right column?
When someone clicks on the contact us text link, can we send them to the tools > import > migrate site flow for the site they purchased the upgrade on?
when you press Restart Migration button, can we go to the plugin landing page?
