There's no confirmation of a "wipe" coming with this migration next week. The only thing we know is that the background simulation servers (and presumably the matchmaking servers) are being moved to the same as the PC test servers. However, if they do wipe our ships, I would only guess they would either send you back to the last station you docked at or to the starter world.
Pretty sure I saw it confirmed somewhere there is definatley a wipe. But... they are going to pay you back in credits to compensate for any assets you loose i.e ships you have.
EDIT: Found it. David Braben answered it in his AMA on reddit. First question, Answer 15.
