2.7 Upgrade Guide

[sonicviz]

Hi,
Is there a proper upgrade guide anywhere?

All I've found is the readme:
If you have a Standard License:
1. In Unity, File -> New Scene
2. Delete the NGUI folder from the Project View.
3. Import NGUI from the updated Unity Package.

and a video:

But not very much explanation of the order of fixing things.
There's a few threads but it seems like they all have bits and tips that would be useful.

It would be useful to have it all pulled together rather than the treasure hunt it seems at the moment.
I'm testing a small upgrade atm and unsure of the order.

Opened scenes, resaved.
Dragged prefabs, resaved.

What's Upgrade Widgets on the menu do? When is it useful to apply?
All my widgets are all over the place, so scratching my head trying to figure out why and what the fix is to get them back.

Glad I tried on a small test project fir rather than the couple of big ones I need to convert!

Upgrade Widgets replaced old components like UISlicedSprite and UITiledSprite with a UISprite, set to the appropriate type.

Don't forget to hit Apply on the prefabs after dragging them in and doing the Upgrade via the menu. Make sure that all game objects are actually enabled -- auto-upgrade won't take place if they aren't.

Thanks.

But to answer my original question: There is no single comprehensive guide to upgrade from 2.7?

There have been posts about it but no centralized one aside from http://www.tasharen.com/forum/index.php?topic=11.msg27296#msg27296
