Step 2 : Unzip the downloaded latest release into a directory on your local machine or in a separate directory at your convinent (In this example we saved in  directory/root/wordpress).

Step 3 : Go to your website root directory (i.e.) /var/www/html/wordpress.Delete the following directories ‘wp-admin’ and  ‘wp-includes’.

#cd /var/www/html/wordpress/

#rm –rf wp-admin wp-includes/

Step 4 : Now,Copy the ‘wp-includes’ and ‘wp-includes’ directories from the unzipped new version WordPress to the website root directory(which replaces the directories deleted in step 2 at website root directory)

#mv /root/wordpress/wp-admin /var/www/html/wp-admin/

#mv /root/wordpress/wp-inicludes /var/www/html/wp-includes

Step 5 : After step 4, dont delete any files or directories in the website root directory.Here, we going to copy all the files from unzipped new version WordPress directory to existing ‘wordpress’ website root directory (by this act we overwrite the existing files with same name)

#mv /root/wordpress/* /var/www/html/wordpress/

optionally, we can also backup the ‘wp-content’ of new version as backup before copying to current website root directory.

Step 6 : Your wp-config.php file will not be affected because wordpress default config file will be wp-config-sample.php.Investigate wp-config-sample.php for any updates to change in wp-config.php file.
