Question

Can we migrate ASP applications to Azure Web App ?

Please help

Answer 1

Thanks for follow up!

On-premise SQL Server connection: Once you migrated your ASP application to Azure App Service Windows container you can use Regional Vnet Integration and SQL Authentication to authenticate between your application and database.

As mentioned in the official doc: https://learn.microsoft.com/en-gb/azure/app-service/web-sites-integrate-with-vnet#regional-vnet-integration

On-premise file-share: As of today there is restrictions connecting to on-premise file share and this is not supported. Please refer to similar post for more details on this.

Thanks for replying and clarification. If you want to migrate the legacy on-prem legacy classic ASP application you can use Docker on Azure App Service which gives you many benefits like better SLA, scalability etc.

You may refer to article Containerize and Migrate Legacy Classic ASP to Azure App Service on explaining on migration of on-prem legacy classic ASP application by containerizing and then hosting it to Azure App Service by using below steps:

• Setup Classic ASP Application
• Create Dockerfile in the same application folder
• Create local Docker image
• Push the Image to Azure Container Registry
• Create Azure Web App using Docker image

You may also refer to the step-step instructions outlined in this blog on How to run classic ASP on Azure Web Apps

Thanks for reaching here! If I have understood right you want to migrate ASP.NET app from on premises to azure app service.

• You may refer: This quickstart which shows how to migrate an ASP.NET web app from on-premises to Azure App Service.
• You can also assess any app with an endpoint scan and download the Migration Assistant and start your .NET and PHP app migration to Azure App Service. Once your endpoint assessment is completed, we support the step-by-step guided migration of .NET and PHP apps only through the local Migration Assistant. Get detailed, code-based assessments and a walk-through of the migration process.

There is nothing different in terms of the Dockerfile for connecting to an on-premises SQL Server as opposed to a SQL Azure DB. The connection string can be externalised using App Settings. You need to connect to your on-premises SQL db using SQL Authentication.

Here is an example contents of a Dockerfile for shipping an app (this was generated in Visual Studio 2019)

FROM mcr.microsoft.com/dotnet/framework/aspnet:4.8-windowsservercore-ltsc2019
ARG source
WORKDIR /inetpub/wwwroot
COPY ${source:-obj/Docker/publish} .

Further you need to configure Regional VNET Integration to be able to reach the on-premises SQL Server.
