Please read this whole thing, as I tell the instructions, but suggest some things after.
Click tools, Axe Manage Presets. Click ok on any warning screens.
Click once on the first preset you want to move.
Use the scroll bar on the bottom to scroll right to the last preset you want to move.
Hold the shift key on your keyboard and while holding, click the last preset you want to move. All presets between the first and last preset should turn blue meaning they are selected.
Carefully click and hold any selected preset and while holding, drag the selection to the right edge of the Manage window. You should start scrolling over and should see the presets show where they will move to. Once they are in the position you want, let go of the click.
Wait and be patient for the operation to complete. Do not click things, do not play your guitar, do not adjust things on the front panel.
If you aren't familiar with clicking and dragging, I suggest scrolling toward the end of the list and moving 1 preset at a time first, until you get used to the action. Then try a small selection, maybe 8 or so, with the click-shift-click method I described.
Even after getting confortable with this, I'd suggest moving smaller amounts of presets at a time, rather than all 384 or however many you are trying to move.
