If you really have to move it, then you can "gently" move it to the new house.
When I say gently, I mean that putting the yeast back into suspension by gently swirling the fermenter is generally considered ok (breweries and home brewers do this to kick-start a stuck fermentation. We used CO2 to gently blow yeast back into suspension, after removing the bottom half of the yeast cake with all the sludge, from the bottom of the conical on a stuck fermentation, worked a charm)
I would try and avoid driving on bumpy roads that will "shake" your beer a lot.
A couple of worries:
If you are racking to secondary and then moving immediately, flood the secondary with CO2 to avoid aeration / oxidation when you move.
Beer spilling out of the airlock
Safest bet : stop worrying and bottle it
I doubt there would be any problems if you bottled only 1 week into the secondary. A lot of home brewers skip the secondary and bottle from the primary (me included in the summer months).
