Hi Manish,
The VB6 application was written using RDC COM SDK which was available and supported til CR XI R2.
From CR 2008 RDC COM SDK has been completely deprecated and is no more supported.
There is no upgrade or migration path. With CR 2008 onwards only .NET and JAVA SDKs could be used.
You would have to re-write the code using .NET SDK.
All the resources for .NET SDK and plenti of sample codes are available, just search through forums.
Also, CR 2013 does not have any SDK. You could design the reports with CR 2013 and use
SAP Crystal Reports for Visual Studio (which works with VS 2010, 2012, 2013) to develop your applications.
Here are few helpful articles
