Exporting Photo from Lightroom CC to Lightroom Classic

I import and edit photos on Lightroom CC, but when I am at home, I like to work furtheron in Lightroom Classic because of (still) more extensive possibilities in Lightroom Classic.

From Lightroom Classic to Lightroom CC is easy and done by migrate in CC from Lightroom Classic. But  how is it in the other direction. I can't find a way in Lightroom Classic to migrate from Lightroom CC.
