   now i am using wp 3.3, but wanna try the latest version of wp:)
   i am afraid will the latest version destroy some of my data?
   since the table structure of 3.3 and latest version may be different:(

   Version 3.3 to 3.4.1 should be a painless upgrade.

   But just to play it safe (safe is good), before upgrading it is always recommended that you make a full file and database backup first.

   - Review this post to see if any other that applies to you.

   - Switch to the Twenty Eleven theme and deactivate all of your plugins.

   - Upgrade any themes or plugins.

   - Then perform the automated upgrade, reactivate your plugins, and switch back to your theme.

   If anything goes horribly wrong (it shouldn't) just restore your file and database backups. That will put your installation back to the way you were prior to the upgrade.
