How to transfer gnucash data and accounts tree from gnucash running on windows to gnucash running on linux?

[Frederic Monestel]

Hi All,

I am going to install the new gnucash 2.4.8 on a linux laptop.
But I would like to import all my data and account tree I have been using
for a while on gnucash 2.2.9 (running on my windows machine).
Anybody could shed some light on the simplest way to do this?

And to make things easier I want to start using a database back-end to
store my data.
Is there any best practice tutorial on how to use the database back-end?
I would particularly like to understand how your data and the accounts tree
are stored in the database?

Many thanks for your help and keep up the good work!
