 # Azure Lab Services to Azure DevTest Labs Transition Guide
 
-When you transition away from Azure Lab Services, DevTest Labs (DTL) is a first party option that can be considered. This document outlines when to and not to consider transitioning to use DevTest Labs. An outline of steps to follow is also included.

-DevTest Labs is targeted at enterprise customers. The primary scenario for which DevTest Labs is designed is the test box scenario, where a professional developer needs temporary access to a virtual machine (VM) that has a prereleased version of the software they need to test. A secondary scenario is professional developer training, when a developer needs temporary access to a VM for internal training.

 ### When should a customer consider using DevTest Labs?
 
-- Customer needs access to Linux VMs - DevTest Labs is the only first party service that provides access to Linux. Cloud PC, Azure Virtual Desktop, Microsoft Dev Box don't provide access to native Linux VMs. 
-- Customer needs to use an image with nested virtualization - DevTest Labs works well with images that use nested virtualization because it provides a dedicated VM for each student. Nested virtualization isn't well-suited for multi-user session VMs because there's no concept of isolation between user sessions. 
-- Technical Computer Programming classes - DevTest Labs resources are available using the Azure portal. Only students comfortable with the Azure portal should use DTL. DTL APIs can be used if you want to create a custom portal to access DTL VMs outside of the Azure portal.

-### When should a customer not use DevTest Labs? 
 - Customer requires extensive cost controls, including user quota and limits on the number of VMs a user can have. DevTest Labs doesn't have any ability to restrict access to a VM based on a quota granted per student.
-- Customer requires complex start and stop schedules. DevTest Labs is designed for enterprise developers; it supports daily start and stop schedules. 
-- Customer requires flexible login methods. DevTest Labs requires that the user exists in the Microsoft Entra ID tenant for the subscription in which the lab is hosted. RBAC permissions are used to control who has access to labs and VMs.

-## Frequently Asked Questions 
+## Frequently Asked Questions
 
 **What is the cost model?**
-There are no costs for using the service; it's free to use. Customers are charged for resources used by the DevTest Labs service. This cost includes, but isn't limited to, the cost of storage, networking, and running time for any VMs in a lab.

 **Does DevTest Labs provide cost reporting?**
-DevTest Labs is integrated into [Microsoft Cost Management](/azure/cost-management-billing/costs/overview-cost-management) for cost budgeting and analysis.  [Allow tag inheritance and add tags to lab resource](/azure/devtest-labs/devtest-lab-configure-cost-management) to track per-lab costs.

 **Does DevTest Labs support nested virtualization?**
-Yes. 
- 
+Yes. Check the [VM series](/azure/virtual-machines/sizes/overview) documentation to verify nested virtualization is included in the list of supported features.

 **Does DevTest Labs support custom images?**
-Yes. We recommend [connecting your DevTest Labs to a Shared Image Gallery](/azure/devtest-labs/configure-shared-image-gallery).  The Shared Image Gallery can be the same one that is connected to your Azure Lab Services lab account or lab plan.

    1. Using advanced settings, multiple identical VMs can be created at once.
    1. Using advanced settings, set the expiration date for [claimable VMs](/azure/devtest-labs/devtest-lab-use-claim-capabilities). VMs will automatically be deleted after their expiration date and avoid unnecessary storage charges.
