Hola charrame,
My Spanish is non-existent so I turned to Google translate to help me out. According to that, this is what you need:
I would like to export places, organizers and events to another TEC installation. Which is the best way?
In your WordPress installation go to Tools > Export and you will be able to export them separately. (screenshot)
To import them on the other website go to Tools > Import. If you have not installed the ‘WordPress Importer’ plugin yet you will have an option to do that there. (screenshot) When it is installed and activated you will have the chance to import them. It is recommended to import them in the following order: venues, organizers, events.
Let me know if you have further questions on this topic.
Cheers,
Andras
