Any way to update Language of basic data?

[Michael Loughlin]

I have a site which was installed in English, and we now wish to have the default language as Spanish.

Unfortunately a lot of the basic data has been initialised in English, and I can't see a way to import or update this data in Spanish.

Anyone know of any way to do this, without reinstalling.

Alternatively, is there a way to export the CiviCRM content, and import it to a correctly configured but "empty" site?

Many thanks,

Michael.
