 The following App Service Environment configurations can be migrated using the migration feature. The table gives the App Service Environment v3 configuration you'll end up with when using the migration feature based on your existing App Service Environment. All supported App Service Environments can be migrated to a [zone redundant App Service Environment v3](../../availability-zones/migrate-app-service-environment.md) using the migration feature as long as the environment is [in a region that supports zone redundancy](./overview.md#regions). You can [configure zone redundancy](#choose-your-app-service-environment-v3-configurations) during the migration process.
