Conversion of crystal report of Desktop application to web application's crystal report

I have got a desktop application which was build in vs200开发者_JAVA技巧5, now i am doing conversion of it to web application (vs2008). i have got around 40 crystal reports in it (desktop application).

please tell me can i use them (rpt files) directly in web application or i will have to create all new reports?

please provide me solution or give me some good URL which can help me.

There is no need for creating new reports you can use the rpt files in the web application just as it was a desktop one and regardless of the version of VS.

All you need is to install Crystal Redistributable packs on the server that is hosting the application.
