If your hives are as active as mine then I'd say it's back to moving them 3ft a day. And given then 3ft is just over 0.9m, you'll be looking at over 66 days before you complete your move. Phew... It would probably be easier and quicker to move them somewhere 3 miles away for a few weeks and then move them back again.
1 They have probaly lost out over the past few months on some sun/ warmth due to been close to a hedge / fence and therfore not getting the low winters sun.
2 They will be further away from the neighbours
I did think about over a couple of days moving them into my trailer and then it would be a simple 30 second job to move them the 2/3 ft en mass (4 hives) in my trailer.
