Organizations using Azure Reserved Virtual Machine Instances for cost optimization face a concrete deadline: as of July 1, 2026, Microsoft will stop selling and renewing Reserved Instances for fourteen older VM series. Those who do nothing will pay the full pay-as-you-go rates after the current reservation expires, which can be up to 72 percent higher than the reserved rates.
This is not something for the distant future. It is a change that requires action now, depending on when your current Reserved Instances expire. For IT managers, CIOs, procurement and contract managers with Azure in their environment, it is crucial to quickly assess the impact and make an informed decision before the deadline.
What exactly changes as of July 1, 2026
Microsoft has confirmed that as of July 1, 2026, new purchases and renewals will no longer be possible for Reserved Instances of the following VM series:
One-Year Reserved Instances (no longer available): Av2, Amv2, Bv1, D, Ds, Dv2, Dsv2, F, Fs, Fsv2, G, Gs, Ls and Lsv2.
One-year-old and three-year-old Reserved Instances (no longer available): Dv3, Dsv3, Ev3 and Esv3.
Important to understand: existing Reserved Instances will not be terminated. They remain valid until the end of the originally purchased term and continue to provide the reservation discount until that date. Only after expiration, and if no alternative has been arranged, will the associated workloads revert to pay-as-you-go rates.
The change does not affect new or current VM generations. Microsoft is clearly steering organizations towards more modern VM series and alternative cost optimization models such as the Azure Savings Plan for Compute.
Why Microsoft is taking this step
The deprecated VM series run on hardware that is approaching the end of its economic lifespan. Various families, including the Dv2 and Ev3, have been marked as obsolete in Azure Advisor for some time. Discontinuing Reserved Instance purchases is a logical next step: the financial incentive to remain on obsolete hardware disappears, after which migration to more modern series is the only sensible course of action.
For organizations, this entails not only a cost risk but also a technical risk. Older VM series run on processor generations for which support and security updates are becoming limited. Compliance frameworks such as ISO 27001, NEN 7510, or sector-specific standards may impose requirements for running on actively supported infrastructure, something that is becoming increasingly difficult to guarantee with continued use of these outdated series.
The financial impact if you do nothing
The financial risk of inactivity is concrete. Reserved Instances typically offer discounts of 40 to 72 percent compared to pay-as-you-go rates. Anyone who does not switch to an alternative discount model after an existing reservation expires pays the full on-demand price.
For organizations with substantial Azure workloads on the affected VM series, this could result in a significant increase in the monthly cloud bill, structurally rather than as a one-off. Furthermore, the option to quickly extend a final reservation will expire once July 1, 2026, has passed. There is no grace period.
Three options to respond to
Microsoft describes three routes in the official transition guide. The choice depends on your current reservations, the nature of your workloads, and your long-term cloud strategy.
- Switching to Azure Savings Plan for Compute
The Azure Savings Plan for Compute is the most flexible alternative. Instead of linking a discount to a specific VM family or region, the discount is calculated based on a fixed hourly rate of compute spending. This provides room to switch VM series, scale, or migrate without losing the discount benefit.
Existing Reserved Instances can be exchanged for a Savings Plan via Microsoft's trade-in scheme — a route worth considering if your workloads change frequently or if migration to another VM series is likely.
This option is best suited for organizations that want flexibility, are considering modernization, or prefer not to lock into a specific VM configuration.
- Migrating workloads to a more modern VM series
The most logical long-term strategy is to migrate to a current VM generation, such as Dv5, Ev5, or Fsv2 successors, and to purchase a new Reserved Instance or Savings Plan for this purpose. Modern VM series generally offer a better price-performance ratio and provide renewed access to full discount structures.
This route requires preparation: a migration plan, compatibility testing, and alignment with application owners. Those who combine this with broader modernization trajectories can serve multiple goals simultaneously.
- Extend a final reservation before July 1, 2026
Do you have stable workloads on the affected VM series and do you not expect any changes in the short term? Then Microsoft still offers the option to extend a one-year or three-year Reserved Instance before July 1, 2026. That extension will be honored for the full term, even after the deadline.
This is the most conservative option and suitable if you want to buy sufficient time to develop a migration strategy. However, keep the end date of the extension in mind: a three-year extension runs until 2028 or 2029, after which migration will still be necessary.
How do you know if your organization is affected?
Check your situation via the Azure Portal:
Navigate to Reservations and filter by Product type: Virtual Machines. View the VM family and the expiration date of each reservation. Is the VM family in the list above and does the reservation expire after or around July 1, 2026? Then action is required.
Next, check the actual usage of the reservation via Cost Management + Billing. A reservation that is already not being fully utilized warrants reconsideration in any case, regardless of the deadline.
Practical recommendations
For organizations that want to take action now:
- Take stock immediately which Reserved Instances you have, on which VM series they run, and when they expire. Without this overview, you cannot make an informed decision.
- Determine per workload whether migration to a more modern VM series is feasible within the available time. Not all workloads are equally easy to move.
- Calculate the financial impact of the three options for your specific situation. The outcome varies by environment, VM series, and usage pattern.
- Keep a close eye on the deadline. There is no extension and no exception after July 1, 2026. Those who are late will automatically revert to pay-as-you-go rates.
- Involve an independent specialist during the analysis. The choice between a Savings Plan, migration, or a final renewal has direct financial consequences in the medium term and deserves more than standard advice from your Azure partner.
Ready to see how Snowflake works?
The abolition of Reserved Instances for fourteen Azure VM series as of July 1, 2026, is a concrete change with direct financial consequences for every organization that uses this discount structure. The deadline is strict, the choices are limited, and the impact of inaction is significant.
The three available routes—switching to an Azure Savings Plan, migrating to a more modern VM series, or a final renewal before the deadline—each require different preparation and suit a different type of organization. Which route best fits your situation depends on your workloads, your migration plans, and your long-term Azure strategy.
Those who make this decision carefully and in a timely manner retain control over their cloud costs. Those who wait pay the price.
