In case Rave Reports is the report solution for your Delphi or C++Builder applications, you will find out that Rave Reports is no longer there. Delphi and C++Builder developers has been complain for a while about Nevrona support, this is not different now. At this point Nevrona didn’t released Rave Reports for XE3 and there is no news on their website.
FastReport has been present in Delphi and C++Builder since XE2 and it’s part of XE3, of course you are thinking about the painful migration process, time and resource necessarily to make the migration. The time and resource is something that only you will be able to determine, the migration of your reports can be done through FastReport. FastReport provide a tool that convert reports created with Rave, QuickReport and ReportBuilder to FastReport. I tried this convertor last year and I was able to migrate a simple report from Rave to FastReport, give a shoot and see how complex reports can be converted using this tool.
In case you have problems to convert your Rave reports, visit FastReports forum. If you already converted reports through the Fast Report convertor, please share your experience on the comment session, it will help others.
