How do I sync Glo and AuraHD?

Hi

I have been using my Glo mostly, but now I decided to start using my Aura HD frequently which brings the issue of keeping thr books and the shelves in sync between devices.

What is the best way to keep the shelves and everything else in sync between these 2 devices? I only use sideloaded books so online thing is not an option for me.

Can I just copy my .kobo folder between these 2?

I use Calibre as my library manager.

thanks
