Current beekeeping problems

[omnimirage]

I've come to learn that the location that I've been keeping my bees is not good for making honey. I've found a much better location, and need to move my beehives up there.

It's quite a distance and I will need a trailer. I'll be moving 12-15 hives, all of them are 2 supers deep or less, except 2, which are at 4. I'm thinking what I'll do is get a bottom board, and separate the 4 deeps into two separate closed units, then rebuild them into 4 deep when I arrive at the property.

All the hives are quite full of honey, I presume I should do a honey extraction before I make the move?

I have a dilemma in that I have a number of nuc colonies that are full and desperately need to be moved into a bigger box, but they use deep frames and I don't have any deep boxes. Really unsure about how to proceed with this... I do have deep boxes that are currently being used as a honey super on other hives, I figure I could take that off, put a bottom on that and use it as a deep.. Is there some sort of method I could use to put the deep nuc frames into a medium brood box?

You can put the deeps in 2 mediums and they will draw comb on the bottom bars to fit the boxes and stop there. Then trim that bit off when you move them back to deep boxes. If they lay brood on the extensions, it will likely be all drone, so no workers lost.

I should have specified that I don't have, nor plan, to use deep supers anymore; I just happen to have these bees in deep supers from last year. Wish it were that easy!

I don't understand your problem---on the one hand you say your location is not a good one for honey production and then you tell us of your  hives being stuffed with honey.  I assume that when you say honey, you don't mean that it's from having been fed sugar syrup.
 
In any event, it's always best to transport hives when they are post extraction. (Don't extract the brood-box)  It's simply a matter of back work that you want to eliminate.  In addition, bumps on the road while travelling, can separate the different supers and the bees that get shaken up in that situation don't take to the adjustment too kindly.  The best method, IMHO, is to reduce all the hives to one broodbox for moving.  They might be crowded in so be sure that you don't have them closed in so tightly as to die from suffocation. After arrival at their new location, you can replace the empty supers.
You might consider dividing each of the hives on 4, into two new hives and give each new family a frame of brood with eggs to raise their own new queens.
Considering that your seasons (southern hemisphere) and ours (northern hemisphere) are reversed, I assume that you are in the middle of the productive time of year.  But I don't know enough details about the length of your summer and when your honey-flows end, to know if you've got enough time for the whole business to stabilize after the move.
