I autoanswer me, in case my experience is ueful for somebody:
Yes, we can import Kjots notes from the «New note from text file» command, in the File menu, in Kontact’ Knotes section or right clicking in Knotes Icon in the system tray if we have launched Knotes standalone.
In the file picker we’ll need to delete «Text File» in the filter box, go to the folder which notes we want to import and select the ones we want. In the file picker we can only see the file names, not the notes’ content, o perhaps the most rapid way is to import all of them and delete the ones we don’t want, if any.
The only issue is that it seems Knotes can’t imported formatted notes (those with colors, backgrounds, marked and formated text, paragraphs, etc) and keep the format we gave them; it will only import them as plain text, but keeping all the HTML code, so perhaps in future versions on Knotes our notes will recover the format.
If there’s a better way to do the import, please, tell us.
Regards.

I recently update my Kubuntu to 15.10 and can't find KJots. It is not in the repository. Where can I find the actual version?
