How hard is it to upgrade an Azure virtual machine [closed]

Question

Let's imagine I create an Azure virtual machine. Say a small one initially.

Later on I decide that the perf of this machine isn't cutting it. I want to upgrade to a larger machine more powerful one.

Given that I've already fully configured this machine to work the way I need it to, how quickly \ easily can it be upgraded so say a medium machine?

Answer 1

It is very easy. You go to the portal and configure/settings/virtual machine size. The instance will reboot once (depending on your application that can be an issue or take time) and the virtual hardware will be changed.

Answer 2

From PowerShell, changing Virtual Machine size is trivial:

Set-AzureVMSize [-InstanceSize] <String> -VM <IPersistentVM> [ <CommonParameters>]

You then need to call Update-AzureVM to have the changes take effect. So... to go from Small to Medium, you can retrieve your VM information, update the size, and then update the VM based on the size change:

Get-AzureVM -ServiceName "YourServiceName" -Name "yourVMName" | Set-AzureVMSize "Medium" | Update-AzureVM
