Hi apollo7,
I will try to answer your questions one by one
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?
Yes. Better Create your companies folder under ISV and then use IIS Redirection and just point to existing application. OR you can create another website, assign it a dedicated app pool and then move your applications there and then you can map your companies folder under ISV to that website by Redirection.
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?
Yes.
I have read forum posts that indicate that I need to copy a dll file under the bin folder - is this always the case?
No.
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.
Most probably you don't have to change the applications if they are running as expected outside of CRM.
