Jaspersoft provides commercial support when you want to use a commercial edition. The community could provide help when you want to use a commercial edition. If you want to leave the commercial edition, you can only find help in the community. No editor, as far as I know, provide help to leave them. As long as your report dont use any of the commercial edition feature (fusion charts, fusion widgets, fusion maps, HTML5 high charts, domain queries, adhoc views, adhoc reports, dashboards, ...) the report sould be compatible with the community edition. So, exporting the repository and reimporting it in the community should do the job.
