How can i update my theme safely?

Go to your themeforest account and in the download page, re-download the theme (updates are free).
Then go to your admin page > appearance > themes , deactivate and remove current theme?and re-upload new version.

Note:?You are just replacing theme files, so your setting, customization and contents are safe in the database, but you could also?backup your website using WP DB-Manager?just in case.

After updating your theme, please hit “Save all options” button in the Option panel because theme needs to re-cache options after each update.
(screencast is also available)
