Moving ASP.NET applications under the ISV folder

There are several custom applications that were written and deployed on another server.  I would like to move these from the old server to our new server.  These applications were added to subfolders under the ISV folder in IIS.  The actual aspx files are located under C:\Program Files\Microsoft Dynamics CRM\CRMWeb\ISV\ and then there are folders under ISV on the C:drive for each custom application.

My questions are:

Can I simply create folders under C:\Program Files\Microsoft Dynamics CRM\CRMWeb\ISV\ on the new server and copy the aspx, aspx.cs and other related files?

Under IIS, can I create a virtual directory under the ISV folder (under Microsoft CRM) and browse out to the default.aspx for each application?

I have read forum posts that indicate that I need to copy a dll file under the bin folder - is this always the case?

What I am looking for is a process that I can document and use to move ISV applications from one server to another. I have done this for asp.net applications that I have created but that these had the files under the inetpub folder and I simply created a virtual directory under Microsoft CRM and called the application aspx from an IFRAME in CRM.

These run under the Sales nav bar and open up new forms with MSCRM.  I have access to the source code for each application if that might be need to be modified when moved to a new server.

I am researching this but any help would be very much appreciated.

Thanks
