 Ensure you understand how migrating to an App Service Environment v3 will affect your applications. Review the [migration process](migrate.md#overview-of-the-migration-process-using-the-migration-feature) to understand the process timeline and where and when you'll need to get involved. Also review the [FAQs](migrate.md#frequently-asked-questions), which may answer some questions you currently have.

 The recommended experience for the migration feature is using the [Azure portal](how-to-migrate.md?pivots=experience-azp). If you decide to use the Azure CLI to carry out the migration, you should follow the steps described here in order and as written since you'll be making Azure REST API calls. The recommended way for making these API calls is by using the [Azure CLI](/cli/azure/). For information about other methods, see [Getting Started with Azure REST](/rest/api/azure/).

 On the migration page, the platform will validate if migration is supported for your App Service Environment. If your environment isn't supported for migration, a banner will appear at the top of the page and include an error message with a reason. See the [troubleshooting](migrate.md#troubleshooting) section for descriptions of the error messages you may see if you aren't eligible for migration. If your App Service Environment isn't supported for migration at this time or your environment is in an unhealthy or suspended state, you won't be able to use the migration feature. If your environment [won't be supported for migration with the migration feature](migrate.md#supported-scenarios) or you want to migrate to App Service Environment v3 without using the migration feature, see the [manual migration options](migration-alternatives.md).

 When the previous step finishes, you'll be shown the IP addresses for your new App Service Environment v3. Using the new IPs, update any resources and networking components to ensure your new environment functions as intended once migration is complete. It's your responsibility to make any necessary updates. Don't move on to the next step until you confirm that you have made these updates.

 ## 4. Delegate your App Service Environment subnet
 
 App Service Environment v3 requires the subnet it's in to have a single delegation of `Microsoft.Web/hostingEnvironments`. Previous versions didn't require this delegation. You'll need to confirm your subnet is delegated properly and/or update the delegation if needed before migrating. A link to your subnet is given so that you can confirm and update as needed.
