If you're looking for information about assessing web apps for migration to Azure App Service, review the [assessment support matrix](concepts-azure-webapps-assessment-calculation.md). ## Migration options You can perform agentless migration of ASP.NET web apps at-scale to [Azure App Service](https://azure.microsoft.com/services/app-service/) using Azure Migrate. However, agent based migration isn't supported. ## Limitations - Currently, At-Scale Discovery, Assessment and Migration are supported for ASP.NET web apps deployed to on-premises IIS servers hosted on VMware Environment. - You can select up to five App Service Plans as part of single migration. - Currently, we don't support selecting existing App service plans during the migration flow. - You can migrate web apps up to max 2 GB in size including content stored in mapped virtual directory. - Currently, we don't support migrating UNC directory content. - You need Windows PowerShell 4.0 installed on VMs hosting the IIS web servers from which you plan to migrate ASP.NET web apps to Azure App Services. - Currently, the migration flow doesn't support VNet integrated scenarios. ## ASP.NET web apps migration requirements Azure Migrate now supports agentless at-scale migration of ASP.NET web apps to [Azure App Service](https://azure.microsoft.com/services/app-service/). Performing [web apps assessment](./tutorial-assess-webapps.md) is mandatory for migration web apps using the integrated flow in Azure Migrate. Support | Details --- | --- **Supported servers** | Currently supported only for windows servers running IIS in your VMware environment. **Windows servers** | Windows Server 2012 R2 and later are supported. **Linux servers** | Currently not supported. **IIS access** | Web apps discovery requires a local admin user account. **IIS versions** | IIS 7.5 and later are supported. **PowerShell version** | PowerShell 4.0 ## Next steps - Learn how to [perform at-scale agentless migration of ASP.NET web apps to Azure App Service](./tutorial-modernize-asp-net-appservice-code.md). - Once you have successfully migrated, you can explore the following steps based on web app specific requirements: - [Map existing custom DNS name](../app-service/app-service-web-tutorial-custom-domain.md). - [Secure a custom DNS with a TLS/SSL binding](../app-service/configure-ssl-bindings.md). - [Securely connect to Azure resources](../app-service/tutorial-connect-overview.md). - [Deployment best practices](../app-service/deploy-best-practices.md). - [Security recommendations](../app-service/security-recommendations.md). - [Networking features](../app-service/networking-features.md). - [Monitor App Service with Azure Monitor](../app-service/monitor-app-service.md). - [Configure Microsoft Entra authentication](../app-service/configure-authentication-provider-aad.md). - [Review best practices](../app-service/deploy-best-practices.md) for deploying to Azure App service.
