What should I check before moving an ASP.NET application to InterServer Windows Web Hosting?
The short answer
Check the exact runtime, database edition, deployment method and required server components. InterServer advertises ASP.NET, .NET Core, SQL Server and Plesk, but matching the application name alone does not prove that your existing application will run unchanged.
In more detail
InterServer's Windows Web Hosting page lists Microsoft web-application technologies, SQL Server and deployment tools. This gives you a starting point for compatibility, rather than an assurance that every version, extension or server-level customization used by an application is supported.
Create a dependency inventory before ordering. Include the target framework, database features, authentication method, background jobs, file-writing paths and any native libraries. A small test application should exercise those requirements, not just display a default welcome page.
Our recommendation is to pay particular attention to database requirements. Ask which edition and capabilities are available for the proposed account if the existing application uses scheduled database jobs, specialized extensions or other features beyond basic queries. Likewise, confirm how the application's scheduled work will run rather than assuming a desktop-style service can be installed.
Choose Windows Web Hosting when the supplied environment fits the application and you want to deploy within that environment. If a required server component cannot be provided, resolve that gap before moving DNS. Keeping a tested copy of the old configuration and a clear rollback path makes the migration decision easier to assess.
