Unable to resize VM, limited quota

Question

Good day, we need to upgrade from Basic A2 (2 vcpus, 3.5 GiB memory) to 4 vCPU, and 8GB memory, but the options are grayed out and says we can't upgrade due to resource constraint. We don;t have a technical support plan, but we need to increase our VM

@Orane Cole Thank you for your query.

Resource Manager vCPU quotas for virtual machines and virtual machine scale sets are enforced at two tiers for each subscription, in each region.

The first tier is the Total Regional vCPUs limit across all VM series. The second tier is the per VM series vCPUs limit, such as the D-series vCPUs. Anytime a new virtual machine is to be deployed, the sum of new and existing vCPUs usage for that VM series must not exceed the vCPU quota approved for that particular VM series. Further, the total new and existing vCPU count deployed across all VM series shouldn't exceed the Total Regional vCPUs quota approved for the subscription. If either of those quotas are exceeded, the VM deployment won't be allowed. You can request an increase of the vCPUs quota limit for the VM series from Azure portal. An increase in the VM series quota automatically increases the Total Regional vCPUs limit by the same amount.

When a new subscription is created, the default Total Regional vCPUs may not be equal to the sum of default vCPU quotas for all individual VM series. This fact can result in a subscription with enough quota for each individual VM series that you want to deploy. It could lack enough quota for Total Regional vCPUs for all deployments. In this case, you'll need to submit a request to increase the Total Regional vCPUs limit explicitly. Total Regional vCPUs limit can't exceed the sum of approved quota across all VM series for the region.

You can refer to this article for more information.

For Azure subscription and service limits, quotas, and constraints you can refer to this article

Since you already mentioned that you don't have any Support Plan enabled for you and as mentioned the only way to do this is to increase the quota explicitly which can be done through Support Ticket.

You can email me with Subject as "ATTN: Preeti" at AzCommunity@microsoft.com and provide me with your SubscriptionID and link to this thread. I can then enable your subscription for one time free support.

Hope it helps.
