i have been given 2 greenhouses, so any tips on dismantling and putting back together would be appreciated. i don't know the size of these greenhouses but i intent to put them up side by side and leave the glass out of the 2 sides to create a big greenhouse.
Two greenhouse person here, 8 x 6 & 8 x 10.

The smaller one was already in the garden but the larger one we dismantled at a friend's garden.
Just a couple of tips echoing Cleo's advice
1) Thick black felt pen, number the uprights, door and roof beams (I even did the glass too!)
2) Take pictures from all angles showing the numbers in situ
3) New glass clips are an essential
If you can erect them as separate greenhouses it will be much better in the long run, maybe have the doors facing each other. A nasty outbreak in the entry greenhouse will transfer to the back one very easily.
