Hello,

Went as expected!
I kept the order of the GPT partitions the same, so no edit of /etc/fstab 
necessary.
And I created the file system with the same settings as the old one.

My root partition is now 32GB
Also made the swap partition bigger,
and have ZFS taking up the rest!


Kind regards,
Coert
