Migrating ASP.NET webpage from IIS 6.0 to IIS 8.5

Hi All,

I've got a web page in my public web server that is still running ASP.NET 2.0 since 2007, since it is running on IIS 6.0 on Windows Server 2003 it does. It supports SHA 256 bit.

Therefore I must migrate it to IIS 8.5 on Windows server 2012 R2.

The database has been changed and migrated successfully by my predecessor to SQL server 2008 R2. But I do not know what steps do I need to take as high level to migrate it succesfully ?

Can anyone please share some list of things that I need to be aware of when migrating web server with different IP, version and name ?

IIS 8.5 (Server 2012 R2) supports running web application under .NET v2.0, you just need to install it since it is not installed by default.

Is there any checklist or caveats that I may need to know ?
Dan McFaddenSystems EngineerCommented:
The question I posted contains 2 lists of items to check and go thru.

The main points are to know the application:

1. What language is it written in?
2. Is there a database component?
3. Are there COM object dependencies?
4. Where is the application directory?
5. Is the site setup in IIS correctly? (for the new version of IIS migrate )
6. Is the AppPool setup in IIS correctly? (for the new version of IIS migrate )
7. Are best practices being following for operating a production website?

I've also written a more detailed to do list in this question:  https://www.experts-exchange.com/questions/28741164/moving-iis-application-database-to-another-server.html

As for caveats:  IMO, the big issue is not knowing the components of the application.  Missing an undocumented something-or-other is a time killer.
