Difficulties upgrading from the Partner Benefits Program to the Partner Extended Program?

I already heard back from the team this is their response:

Thank you for sharing your experience. I understand the frustration, especially when you're trying to maximize the value of multiple benefits purchases and expect them to work seamlessly together. I wanted to clarify a couple of points that may help explain what you're seeing today.

1. Partner Success Core and Partner Success Expanded are separate offers, not upgrade paths

Partner Launch, Partner Success Core, and Partner Success Expanded are sold as separate benefits packages. At this time, there is no upgrade mechanism or prorated credit that allows a partner to move from one package to another during an active term. Partners may choose to purchase more than one package, and when they do, they receive the cumulative benefits included in each offer. For example, a partner that purchases both Partner Success Core and Partner Success Expanded is entitled to the benefits associated with both packages. [partner.mi...rosoft.com]

2. Azure credit redemption has recently changed

Microsoft recently modernized the Azure benefits redemption experience. Under the previous model, partners typically redeemed Azure credits by activating them through a designated user, which created a new Azure subscription. Under the new model, Azure credits are deposited directly into an eligible Billing Profile associated with the same Microsoft Customer Agreement (MCA) Billing Account that was used to purchase the partner benefits package. Existing subscriptions under that billing profile can consume those credits, so partners generally no longer need to create a separate Azure subscription solely to use partner benefits.

3. Credit stacking has some important rules

A Billing Profile cannot hold multiple sets of active credits at the same time. In practice, this means that if a partner purchases multiple packages or has credits from multiple sources, each set of credits needs to be deposited into its own eligible Billing Profile.

4. License redemption has also changed

Cloud benefits such as Microsoft 365 and Dynamics 365 licenses are now redeemed through a modernized, keyless process tied to the billing account used to purchase the offer. As part of this transition, the redemption and assignment experience differs from the historical product-key-based approach that many partners were accustomed to. [partner.mi...rosoft.com]

I hope this helps clarify the behavior you're seeing. If you're running into a specific issue redeeming benefits or associating them with your billing account or billing profiles, please let us know by raising a Partner Center support ticket and we'd be happy to take a closer look.
