Qn re upgrading from old JR to current version

[Patrick0]

I've been asked to migrate a quite old version of Jasper Reports to a new host. I've not come across Jasper Reports before and am not sure if we have the community or commercial version.

Under Tomcat's webapps I can see jar file ReportServlet/WEB-INF/classes/WEB-INF/lib/jasperreports-6.1.1.jar & DynamicJasper-core-fonts-1.0.jar - hopefully that helps identify the version we have.

Can some kind person point me to a guide on upgrading and clarify whether ReportServlet equivalent functionality is now in the community or commercial version?

thanks so much!
