Very little! You can use the in-place advisor editing feature of SMARTASSISTANT. Just select the element you would like to translate, define the source and the target languages, and translate the element.
If you need to translate multiple elements in several advisors, you can export the advisor content in the XLIFF format (XML Localisation Interchange File Format), an XML-based format, to translate the elements with a translation software. The translated XLIFF files can then be uploaded back to SMARTASSISTANT.
