Hello,

There's no api to do such task in iCagenda. Maybe one day (as it's an interesting feature) but i'm currently focus on other major developments for iCagenda itself.

The only way to day is to use PHPAdmin to export tables data, and import those data in the new system after install of iCagenda.
And to transfert the media files in the same folders structure on the new site.

Best regards,
Cyril
