We have a web application created with VS 2008, .NET Framework 3.5 and Crystal Decisions references 10.5.3700.0. The application opens standalone Crystal Reports XI Release 2 and converts them to PDF. Now we need to move this application from Window Server 2008 32 bit to Window Server 2012 64 bit. I am trying to figure out the steps we need to take. My understanding is that we need to re-build the application with the later version of Visual Studio with the appropriate version of SAP Crystal Reports for Visual Studio, the Framework will still be 3.5, is this correct? What version of the VS and CR for VS is best? DO we need to convert the reports to a later version as well, or can they stay as they are? Or do we need to change the code so that the reports are a part of the project? I understand that we need to configure a 32 bit ODBC on the server and install the appropriate Crystal Runtime with the application, and make sure the Framework 3.5 is running. Are there any other server configurations that we need to address? Thanks!
