If the sections can be moved without taking out the glass it will be so much quicker and easier and you are less likely to break the glass.
We have moved our wooden Alton 5 times and I should think the principle is the same.
Door first. Then roof sections. Then sides. Then ends. Have lengths of wood available to brace the bits when you remove sections. Two people make it simple. Do not do it when the wind is blowing. Do not leave it incomplete overnight. If the nuts and bolts are difficult to undo, apply oil to them and leave overnight for them to loosen. Make sure you have plenty of new bolts, clips, etc before you start, so you don't have to go and get some more mid-construction
It is far easier to wash the glass at ground level, especially the inside of the roof sections.
When you reconstruct make sure everything is square. Start by putting the end opposite the door in place and brace it firmly. Then off you go.
In my experience it is inevitable you will hear the tinkle of broken glass. But with luck it will only be one sheet.
