If your JReport Server contains resources earlier than V8 such as reports, visual analysis, library components, dashboards, catalogs, etc., during each server runtime lifecycle when you run such a resource for the first time, the JReport Engine has to first convert the earlier version resource into a current version resource before running the resource. This may result in decreased performance. To avoid this, JReport Server allows administrators to permanently convert resources earlier than V8 in the server resource tree to adapt to the current version.
You have the following two ways to convert resources:
The converting UI is available to administrators only. It is used to convert all resources earlier than V8 in the My Reports folder or Public Reports folder. The converted resources are stored in the same directory.
You can also use rptconv.bat/rptconv.sh located in the <install_root>\bin
directory to convert a resource and a type of resources or all resources earlier than V8 in a directory to current version.
