Unable to increase Virtual Machine Size through Azure Management Portal

Question

I am trying to change the Virtual machine size from - 8 Cores, 14 GB to A 6 - 4 core, 28 GB for one of of my MSSQL Azure IaaS server.

I am getting the following error:

Unable to upgrade the deployment. The requested VM size may not be available in the resources supporting the existing deployment. Please try again later, try with a smaller VM size or smaller number of role instances, or create a deployment under an empty hosted service with a new affinity group or no affinity group binding. The long running operation tracking ID was: 1d8145d1977877978d1d8dffdd045d83.

I understand that there is a limitation on how much one can get from one subscription. However, this is the live server and I have another 4 servers running under same subscription. Is there any way I can move this Virtual machine from one subscription to an another?

Otherwise, what is the right approach on increasing the size of this server?

Please advise the earliest.

Answer 1

I got the answer from Support as :

When customer initially deployed service it got deployed under the cluster which does not support high memory VM's. Since customer is having deployment under the hosted service it cannot be pinned/migrated to a cluster which supports A6 or higher VM size. This is a by design behaviour as of now. Unfortunately, the only way customer can deploy a A6 VM is to delete and recreate deployment with A6 size under the given hosted service. When customer tries to create it, then he/she will be allocated a cluster which supports A6 or higher VM size.
