Update a .NET ASP Site

Job ID: 34472894

Budget: $30 – $250 USD

I'm currently working with a small client, and they recently applied security updates to their Windows Server 2012 R2 server; it broke a process in which they upload packages to the app. I would like you to troubleshoot and fix the issue and then assess moving the app to Azure as a PaaS type app.
