Hello @Marcelo Mintrone ,
Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question.
Yes, VMs that are NOT classic and the VMs that are already migrate to ARM will continue to work even after March 1, 2023. Only classic VMs will not work (will be stopped and deallocated.)
In 2014, we launched infrastructure as a service (IaaS) on Azure Resource Manager. We've been enhancing capabilities ever since. Because Azure Resource Manager now has full IaaS capabilities and other advancements, we deprecated the management of IaaS virtual machines (VMs) through Azure Service Manager (ASM) on February 28, 2020. This functionality will be fully retired on March 1, 2023.
How does this affect me?
As of February 28, 2020, customers who didn't utilize IaaS VMs through ASM in the month of February 2020 can no longer create VMs (classic).
On March 1, 2023, customers will no longer be able to start IaaS VMs by using ASM. Any that are still running or allocated will be stopped and deallocated.
On March 1, 2023, subscriptions that are not migrated to Azure Resource Manager will be informed regarding timelines for deleting any remaining VMs (classic).
Note: This retirement does not affect the following Azure services and functionality:
Storage accounts not used by VMs (classic)
Virtual networks not used by VMs (classic)
Other classic resources other than VMs.
