VM creation in Azure

Question

Hi,

We would like to run a test with one of our on-prem production application that is running on an Hyper-V VM in Azure. we don't want to migrate the current VM to the Azure and we want to live the current production VM on-prem.

We have already the ASR in place and we sync some of our VMs to Azure but we dont want to use this one as well because after we move this Vm to Azure we want to run it without shutting down the production VM.

Do you have any suggestion of how to create a VM in Azure based on copy of an existing on-prem VM without having ANY side effect on the current production environment.

Thanks

Answer 1

Hi,
I would suggest that you use vhdx files to create VMs in Azure.
Please note that to copy the vhdx files you might need to turn off the production VMs, which might bring you some downtime.

Thanks for your understanding.

Answer 2

Hi @Yuhan Deng
Do you mean just simply create a copy of the vhdx file of my on-prem VM and upload it to my Blob storage account in Azure? I thought that Azure VM will only work with First gen VHD files!! Also how can I create a VM from uploaded vhd in my blob storage account? shouldn't we first made an image from m on-prem vhd file?

Thanks

Hi,
To upload a vhd to Azure, you can refer to this:
https://learn.microsoft.com/en-us/azure/virtual-machines/linux/disks-upload-vhd-to-managed-disk-cli
And to create a VM with it, refer to this:
https://learn.microsoft.com/en-us/azure/virtual-machines/windows/create-vm-specialized-portal
And for Gen 2 VM in Azure, this might help:

Thanks for your time.
Best regards,
