I sent an email to support but I thought I'd document here too.
I finally managed to get through the first stage of converting my megabrain from TB8 to TB10. However, I’ve come across another problem. Over 6,000 internal files apparently could not be imported due to file path error ("The files relative path cannot be longer than 150").
Has anyone else experienced this problem?
