Capacity growth restrictions for older generation v1 - v4 Azure VM series

Question

Hello Support Team,

We just received the alert notification email Capacity growth restrictions for older generation v1 - v4 Azure VM series and Starting 31 July 2026, Azure will implement capacity growth restrictions for the v1- v4 VM series as part of ongoing investments in newer-generation infrastructure. As a result, new deployments, capacity expansion requests, and quota increase requests for impacted VM series will not be approved. Quota already approved in existing subscriptions for these VM series will not be affected.

**Impacted VM series and could you please [**Compute optimized: F, Fs, Fsv2

• General purpose: D, Ds, Dv2, Dsv2, Av2, Amv2, B, Bs
• Memory optimized: G, Gs
• Storage optimized: Ls, Lsv Microsoft recommends evaluating newer-generation series (such as v5 or later) for new deployments to ensure hardware availability and performance benefits. Could you please confirm the VM size need any action required for Azure VM resize restrictions and reservations[ Currently VMs Running with Standard F4s v2,Standard D3 v2,Standard_D4as_v4,F8s v2,B2als v2 Sizes]. Please let us know if any action do current VM before the 31,July 2026. Thankyou,

Answer 1

No immediate resize is required before July 31. Microsoft states that these capacity controls affect new deployments, expansion, and additional quota, not existing running VMs or already approved quota.

Standard_F4s_v2, Standard_D3_v2, and Standard_D4as_v4 are in affected Fsv2, Dv2, and Dasv4 series. Standard_B2als_v2 is Basv2, which is not in the published affected list; verify the exact SKU because B and Bs v1 are affected.

Inventory each VM's region, size, quota, and reservation coverage. Keep production VMs running while you test equivalent v5, v6, or v7 sizes for CPU, memory, disk, networking, image generation, and zone support. Request quota for the chosen target family, then schedule a controlled resize; resizing restarts the VM and may require deallocation.

Existing Reserved VM Instance discounts are not cancelled. However, a new size outside the same instance-size-flexibility group may not use the reservation, so review utilization and exchange or refund options before migration.
