In practice probably, but not necessarily. It is, of course, important
that the partitions on each disk that go into the RAID are the same, but
you don't actually have to use the existing partitions. Let's say you
wanted to divide things up so you had swap, / and /home on separate
partitions - you could create the partitions on the new disk the way you
want them, copy the data over, restart, remove the old partitions from
from the original disk, and then create a copy of the new layout on it
to put the RAID on.
That's entirely optional though, if you're happy with your current
layout, keep it.
Oh, and note that it's probably not worth RAIDing the swap, and if you
did want to do that it may require some additional fiddling around.
