Same here. It is the only plugin activated, and does it with multiple themes.
It seems to post the changes, but not going to a screen can be a problem.
OK, something did not like 10 meg filesizes, so I made everything 5 megs and it works well. Maybe an option to change the database name and prefix, as my guy could not get it to work because of that, and that is why I got invloved.
Otherwise, after the hickups, worked well.
For some reason, not all the files, specifically themes are not being transferred. Themes are Genesis, if that makes any difference, but since the whole directory was checked to copy, not sure that would make any difference.
