fear upgrade to 4.2
 

My questions are:
My forum will be in Spanish or have to use other translations?
Template Modifications remain or disappear all the changes?

I know all the steps, if there are any errors I do know ...

1.-Backup my database
2.-downloaded the files from the members area.
3.-The unzip
4.-deleted the file install.php
5 - deleted the file config.php.new to stay with my current config and change nothing of this file
6.-Deactivate all my plugins and products
7.-I close my forum
8.-upload all the files via ftp and rewrite all.
9.-In my browser to the address I http://www.myforum.com/forum/install/upgrade.php
10.-I follow the steps until I open the admin panel.

Ready ... Now I have 4.2 mi Forum

Am I correct?

Updating from what version also I would disable plugins from config not the admin panel
