Hi Razzi,
AFAIK it require some pre-reqs and proper planning, please check the steps I feel should be carried out.
Here's a general outline of the steps you would need to take to migrate resources:
Create an inventory of your ASM resources: Before you begin the migration process, you'll need to create an inventory of all the resources that you want to migrate. This should include information such as the resource type, resource name, resource group, and any associated dependencies.
Prepare your resources: Depending on the type of resource, you may need to make some changes or configurations to ensure that the resources are in a state that can be migrated. For example, you may need to update the configuration of a virtual machine or web app to align with the ARM deployment model.
Create a migration plan: Once you have an inventory of your resources and have prepared them for migration, you should create a migration plan. This plan should include information such as the order in which resources will be migrated, the teams responsible for each resource, and any dependencies that need to be taken into account.
Perform the migration: Once you have your migration plan in place, you can begin migrating your resources to the ARM deployment model. There are a few different ways you can migrate resources, depending on the type of resource. Some resources can be migrated using Azure PowerShell or Azure CLI, while others may require more complex migration steps.
Test and validate: After the migration is complete, you should test and validate that all of your resources are in good working order. It's important to understand that this is a very high level approach and depending on the number of resources, size and complexity, this process could be time-consuming.
Azure migration tool like Azure Migrate can be useful in this case. It can help you assess and plan your migration, track its progress, and validate that your workloads are running correctly after the migration.
Hope this helps.
