[Trisquel-users] Re : Trisquel 9 Graphical ISO available for testing

[lcerf]

Will it be possible to migrate from Trisquel 8 to Trisquel 9? Without wiping  
disk and loosing existing data.

Yes.  In fact, if you are not afraid of alpha version, you can already do  
that:
$ sudo sed -i 's/flidas/etiona/' /etc/apt/sources.list && sudo apt update &&  
sudo apt full-upgrade
