Move Session Onto Different Computer

I've been mastering QTractor, which is a very nice piece of software to use, but I was wondering how I can move my session onto a different computer so I can work on it when I'm at work (during smoko), or go away on holiday?

I tried just moving the session folder onto my netbook, but it didn't seem to like it.

I have a more powerful computer as my primary workstation, as my netbook is a bit old now (2011) and isn't very powerful.

Do I have to do something with Gladish or something? I am using the same OS (Ubuntu Studio 18.04) on both computers, so should be reasonably compatible. I have done a bit of research online, but haven't been able to find much related to QTractor.

Cheers,

Sam
