About SOTA

I have some questions about SOTA

1.What if for example I buy an item with a good awakes can I transfer ALL of that awakes to the new item in one use?or 1 SOTA=1awakes only

2.Can I use different class items to transfer awakes?Ex.Assist class helm awakes transfer to a Jester class helm?

3.Can  I still use Sota even if My items have an awake already?

I hope all of you can answer my questions and sorry for my grammar

1. 1 SOTA = 1 awake only
2. yes. but not helm/suit/weapon/shield to gloves or boots and v/v
