Hello,

We have a server that we use for demo/test of our DNN 2.4 site.  We are trying to migrate to DNN 4.5, but I need to keep the DNN 2.4 site active until we completely move our production environment (currently DNN 2.4) to DNN 4.5

Can the two version of DNN peacefully coexist on the same web server?  I have installed 4.5 on the server (running Windows 2003) and when I try to browse to the site to begin the install process, it fails with the following error:

   Configuration Error
   Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Source File: C:\WebSites\BRMS\Website\web.config    Line: 6

I have successfully installed DNN 4.5 on my local dev workstation as well as some other servers that do not have DNN 2.4.  So, I am wondering if this is possible to get the two versions installed on the same machine.  Would something in my DNN 2.4 setup (web.config or ?) cause this sort of problem?

Thanks for any help.
