### Converting reports of earlier versions into current version

If your JReport product has been updated from a version earlier than V9, when running reports of the earlier version, you may encounter decreased performance due to the JReport Engine having to first convert the earlier version report into a current version report set before running the report. In order to enhance performance, JReport Enterprise Server allows administrators to permanently convert reports of earlier versions in the server resource tree to adapt to the current version.

Report converting applies to reports of all previous server versions.

#### Converting via the Administration UI

The converting UI is available to administrators only. It is used to convert all old reports in the My Reports folder or Public Reports folder. The converted report sets are stored in the same directory.

To convert reports of earlier versions into current version:

1. On the JReport Administration > Reports page, switch to the Converting tab.

2. Specify the folder(s) which contain(s) the reports you want to convert.

3. Specify how to save the converted reports.
   - Replace the Old Repors
     Specifies to replace the old reports with the converted report sets.
   - Save as Ad Hoc Report Versions
     Specifies to save the converted report sets as new report set versions in the resource tree.
4. When done, click OK to start converting.

#### Converting using tool

You can also use rptconv.bat/rptconv.sh located in the `<install_root>\bin` directory to convert a report and a type of reports or all reports in a directory.
