Hello,
It's not so difficult to make an upgrade. I look the update, there 2 sql update.
in first, go to your phpmyadmin and update the Db.
in second, just send the files in your server.
Do not forget it's a pre release, some modification can be made the last minute
For you it's good to make a test.
That's all.
My recommendation before that, do the update in your local server, If your have no problem, go in production.
About the module, it will have no problem.
