Exists a supported Jira import from a database that runs automatically and also imports custom fields?
What we have to do is the synchronisation of a ticket system with Jira. The ticket system is used by our customers (external communicatin) whereas Jira is used by our developers (internal communication). The external tickets have to be imported into Jira after creating and after closing they have to be exported. The ticket system provides the possibility to export and import the issue data in/from a database (possible would also be to export/import in/from a csv file).
