A migrate operation is implemented as a resize operation using the same flavor

new server using the same flavor and copying the contents of the original disk
into a new one. As with resize, the migrate operation is a two-step process for
the user: the first step is to perform the migrate, and the second step is to
either confirm (verify) success and release the old server, or to declare a
revert to release the new server and restart the old one.""")
