How the billing will be when I scale up an Azure reserved instance vm

Hi everyone,
As the title, I'd like to ask about pricing in Microsoft Azure service for reserved VMs.
E.g I have an D2v2 reserved VM and due to the lack of resource, I want to scale up it to D3v2.
=> How pricing looks like? The difference in resource will be discounted as reserved resources?
Thanks

Hi @SonNguyenHoang-9208 ,

here you can see how the reserved instances are applied if there is a resizing in the same VM series (same instance size flexibility group):

Hello, as I read your quote in document carefully, I do understand the thing you mentioned.

You mean that if the initial (RI1) reservation has been occupied by all existing VMs and I need more VMs' resources, I can buy a new (RI2) reservation and combine a1 + a2 for the existing VMs which's needed to scale up.
I dont know if I understand the document correctly?

Thanks

Hi @AndreasBaumgarten ,

Thanks for your response, I see that we can scale up a VM to a bigger size that in the same VM series. But the document does not say about how the pricing will be, (if I dont miss) can you help me or quote the related words?
