jasperreports 5.6.1 backward compatibility

[kursattokpinar]

I was using the 3.7.4 version of jasper reports library and i am planning to upgrade it to 5.6.1 which is the latest version and supports dynamic row generation for outcoming reports. But there exists a lot of jrxml templates in my db which are prepared to use with jasper reports 3.7.4.

Is 5.6.1 provides compatibility to reports those currently works with the version 3.7.4? Or can i do something practical to make them work with 5.7.1 version?

I have just updated from 5.1 to 5.6.  The reports are not opening in iReports designer.
