What to do if a new manager creates a new contract for me?

[#1]

My existing client had some changes in the leadership. The new manager has created a new contract for me. 
I don't want to pay a 20% fee to Upwork as they are not a new client for me. I should be paying 10%...right? What can I do to ensure this?

Thanks for the help and kindness!

Hi Tanima,

I would like to clarify that if you worked with someone under two different companies, those are considered different relationships and your lifetime billings with each company will be counted separately. However, working with someone under two different teams within the same company is considered a single relationship and therefore combined in your lifetime billings.
