+Migrating from Azure Lab Services to Azure Lab Services August 2022 Update requires planning. This article describes process of migrating to the August 2022 Update in detail, and will help you understand the requirements and sequence of steps you should take for a successful migration.
 
 If you're moving from the current version of Azure Lab Services to the August 2022 Update, there's likely to be a time when you're using both lab accounts and lab plans. Lab plans replace lab accounts in the August 2022 Update. Although similar in functionality, lab plans give you more flexibility in how you manage your Lab Services than lab accounts. You can read more about the differences between lab plans and lab accounts in [What's new in Lab Services?](./lab-services-whats-new.md#lab-plans-replace-lab-accounts).
 
 Lab accounts and lab plans can coexist in your subscription and share the same external resources. However, lab accounts and lab plans do not share capacity. You must request new capacity for lab plans even if you have existing capacity for lab accounts.
 
-With all the new enhancements, it's a good time to revisit your overall lab structure. More than one lab plan might be needed depending on your scenario. For example, the math department may only require one lab plan in one resource group. The computer science department might require multiple lab plans. One lab plan can enable advanced networking and a few custom images. Another lab plan can use basic networking and not enable custom images. Multiple lab plans can be kept in the same resource group.
+## Lab scenarios
+
+You cannot migrate existing labs to the August 2022 Update. Instead, you must create new labs. Along with all the new enhancements, the requirement to create new labs provides a good opportunity to revisit your overall lab structure and plan changes where necessary.
+
+Although you cannot migrate existing labs, you can still reuse other assets such as Compute Galleries and images, and any licensing servers.

+  Most schools delete their labs and recreate them each semester (or class session). You can schedule the move to the August 2022 Update during one of these transitions.

-## 1. Create a lab plan 
+  Some schools reuse the same labs each class session and change the student roster. With this approach, you must plan the creation of new labs to transition to, typically at the start of a new session.
+
+## 1. Create a lab plan
 
 Before you request capacity, you must have at least one lab plan in your subscription. If you don't already have a lab plan, you can create a temporary lab plan for requesting capacity, and delete the plan afterwards. Because capacity is assigned to your subscription, it's not affected when you create or delete lab plans. The first time you create a lab plan, a special Microsoft-managed Azure subscription is automatically created.  This subscription isn’t visible to you and is used internally to assign your [dedicated capacity](/azure/lab-services/capacity-limits#per-customer-assigned-capacity).

 Customers are now assigned their own [dedicated VM cores quota](/azure/lab-services/capacity-limits#per-customer-assigned-capacity).  This quota is assigned per-subscription. The initial number of VM cores assigned to your subscription is limited, so you'll need to request a core limit increase.  Even if you're already using lab accounts in the current version of Azure Lab Services, you'll still need to request a core limit increase; existing cores in a lab account won't be available when you create a lab plan.

 #### Tips for requesting capacity
+
 - The time that it takes to assign capacity varies depending on the VM size, region, and number of cores requested. To ensure you have the resources you require when you need them, you should:
-    - Request capacity as far in advance as possible.
-    - Make incremental requests for VM cores rather than making large, bulk requests.  
+  - Request capacity as far in advance as possible.
+  - Make incremental requests for VM cores rather than making large, bulk requests.  
  For example, when you move from lab accounts to lab plans, you should first request sufficient capacity to set up a few representative labs that serve as a proof-of-concept.  Later, you can make additional capacity requests based on your upcoming lab needs.
-- If possible, be flexible on the region where you're requesting capacity. 
+- If possible, be flexible on the region where you're requesting capacity.
+- Make incremental capacity requests. Breaking requests for large numbers of cores into smaller requests gives extra flexibility in how those requests are fulfilled.
 - Capacity remains assigned for the lifetime of a subscription. You only need to request extra capacity if you need more than is already assigned to your subscription.

 ## 3. Configure shared resources  
 
 You can reuse the same Azure Compute Gallery and licensing servers that you use with your lab accounts.  Optionally, you can also [configure more licensing servers](/azure/lab-services/how-to-create-a-lab-with-shared-resource) and galleries based on your needs. For VMs that require access to a licensing server, you'll create lab plans with [advanced networking](/azure/lab-services/how-to-connect-vnet-injection#connect-the-virtual-network-during-lab-plan-creation) enabled as shown in the next step.

     - The lab plan’s resource group name is significant because educators will select the resource group to [create a lab](/azure/lab-services/tutorial-setup-lab#create-a-lab).
     - Likewise, the lab plan name is important.  If more than one lab plan is in the resource group, educators will see a dropdown to choose a lab plan when they create a lab.

 Each of the VM sizes has been remapped to use a newer [Azure VM Compute SKU](/azure/lab-services/administrator-guide#vm-sizing). If you're using an [attached compute gallery](/azure/lab-services/how-to-attach-detach-shared-image-gallery), validate each of your customized images with the new VM Compute SKU by publishing a lab with the image and testing common student workloads.  Before creating labs, verify that each image in the compute gallery is replicated to the same regions enabled in your lab plans.
