I get the 404 error after migrating the window server

We are migrating the old server to the new server. The new product is on Windows server 2016.

All settings have been completed. However, when I tried to enter the website,

The 404 error resource was not found.

For example, the website name will be similar to the server name, but I can use a bad link to access the website, but not the actual link.

Edit:

The old version of Windows was 2008, the actual link is mydomain.com/applicationname/test.aspx, the bad link is mydomain.com/test.aspx.
