Fruit tree question

Fruit tree question

I have a slightly complicated question about transplanting fruit trees. Background: My husband and I bought our first house last spring. I really wanted a small orchard, so that fall we bought four very small fruit trees - two apples and two plums all of which were rated for either zone 2 or 3 (I live in a cold cold zone 4a). We planted them in late september; the ground wasn't solidly frozen until January. Now things have come up, and it looks like we're moving. Because of the type and location of our current house I suspect we'll end up selling to to someone who will use it as a second home near a ski resort - and whoever that is, it's likely they either won't know how to care for my fruit trees, or won't like their location and simply cut them down. So my question is, can I transplant these when I move, and if so what's the best way to go about it? The trees are very very young - the diameter at the base of the trunks is between 1 and 2 inches. And we still have snow on the ground. So I was thinking maybe they haven't had a chance to spread many new roots. Can I dig them up and put them in the giant pots they came in? The pots' diameters are probably 2-3 feet - which is about the spread of the branches on these trees. The problem here is that we have only just started considering this move, so they might be in these pots all summer. I don't mind if their growth is set back a year by being contained - as long as they'll still be healthy enough to grow once they're in the ground again. Alternatively I could dig them up once we know where we're going and I'll be able to transplant them directly to the new house - but then they'll be growing all summer, and would the move be more traumatizing to them then? If there is no good way to transplant these guys I'll just leave them behind and hope for the best - but I really don't think they'd have much of a chance...
