Business Process Flow does not have new UI style after upgrading to Dynamics 365 Update 0.1 from CRM 2015

Hello guys,

I have a DB with CRM 2015 Update 0.2 version.

I upgrade this DB to Dynamics 365 Update 0.1 (version 8.2.1.176) using the import feature of Deployment Manager.

Then I open the existing record which had already been applied business process flow (BPF) in CRM 2015.

The BPF is shown, however, I don't have the new UI design of the BPF : stage color is green, new style of buttons (e.g. Next Stage button)

My current BPF stages still have orange color, the buttons are even hidden.

Do you have any ideas?

Many thanks for your anwers,

Anh
