I have, and I've never sysprepped an existing image before migrating it.
You sysprep when you need to change all the internal machine identifiers and drivers and effectively create a blank slate. I would never want to do that to an existing system I was trying to preserve by migrating it. If I wanted to do that, I would just build a parallel solution and cut over to it.
