A large government organization was told its Enterprise Agreement would not renew on the old terms and that the future ran through the new commerce model. The transition arrived with a short window and very little independent guidance. This is how the onboarding was sequenced so the move protected pricing rather than resetting it.
A government organization running Microsoft 365 across tens of thousands of seats, a growing Azure footprint, and a Windows and server estate inherited across multiple agencies. The legacy Enterprise Agreement was reaching the end of its term and the account team had positioned the move to a Microsoft Customer Agreement for Enterprise as the only path forward. The practice was engaged to run the onboarding as a controlled migration rather than a reset of every negotiated term.
The organization had run its Microsoft estate on an Enterprise Agreement for more than a decade. Pricing, discount levels, and product use rights had accreted over several terms, and a great deal of negotiated value sat inside an agreement structure that almost nobody on the current team had been present to negotiate. When the account team signaled that the renewal would move to the new commerce model, it was presented as an administrative transition. New paper, same relationship, sign here.
That framing concealed real exposure. Moving from a legacy agreement to a Microsoft Customer Agreement for Enterprise is not a like for like port. Discount structures are recalculated, level based pricing is reassessed, and terms that were quietly favorable under the old enrollment do not automatically survive the move. For a public body with procurement rules, budget cycles fixed years in advance, and limited appetite for surprises, an uncontrolled migration risked baking a higher run rate into the next three years of public spending.
There was a second pressure. The enrollment window was short and the internal team had no independent baseline for what the estate should cost under the new model. Without that baseline, every number the account team presented would look reasonable, because there was nothing to measure it against.
The engagement started by building the baseline the organization lacked. The practice reconstructed the true effective cost of the legacy agreement, line by line, including the negotiated discounts and use rights that were easy to overlook because they had been in place so long. That reconstruction became the reference point for the entire migration. The question stopped being what the new model would cost and became whether the new model preserved the value the organization already held.
From there the onboarding was sequenced deliberately. The billing account and tenant structure were designed before any commercial terms were agreed, so the organization moved into a clean structure aligned to its agency boundaries rather than inheriting whatever default the account team proposed. The Azure commitment was sized against real consumption rather than a forward projection, which removed an overcommitment the organization would have funded regardless of usage. Microsoft 365 license counts were rationalized against active assignment before the seats were carried across, so the migration moved the right footprint rather than the historical one.
Price protection was the decisive term. The practice negotiated multiyear protection on the core estate so the migration locked a known run rate into the next three budget cycles rather than exposing the organization to model driven increases mid term. A migration with price protection is a contract. A migration without it is an open invoice.
The organization completed its move to the new commerce model inside the sixteen week window with the migration avoiding an eighteen percent uplift that the initial transition terms would have carried. The savings were structural rather than promotional. The legacy baseline anchored the discount discussion, the rationalized footprint moved only the seats genuinely in use, and the resized Azure commitment matched actual consumption rather than a projection the organization would have paid into regardless.
The billing structure mattered as much as the headline number. By designing the tenant and billing account before agreeing commercial terms, the organization onboarded into a structure that mapped to its agencies, supported internal cost allocation, and gave its finance team visibility it had never had under the legacy enrollment. Price protection across the core estate fixed the run rate for three budget cycles, which for a public body planning years ahead removed the single largest source of forecasting risk in the technology budget.
The engagement reflects the firm's broader record across Microsoft contracts: more than $420M in cumulative client savings, over 340 engagements delivered, and an average 79 percent reduction in audit financial exposure, built on 20+ years of combined practice depth across the Microsoft estate. The figures above are verifiable on a reference call arranged through the practice.
The practice supports public sector and enterprise teams on running the transition to MCA E as a controlled migration that protects negotiated value rather than resetting it. Two analyst calls, no pitch, and an honest read on what the move will actually cost.
