问题
I have a VPS with centOS 6.3 installed on it, i want to change from php-mysqld to php-mysqlnd (native driver) for better performance.
But the problem is that i have a production website on the server with a huge database and phpmyadmin installed to take control of DBs web based. now i'm afraid that if i erase php-mysqld and the install php-mysqlnd i will lost DBs as well as users created for them and i have to config all of them again.
Is there anyway to keep my DBs , Users, Configs , ... during this change ?
Thanks in advance

Actually i found it to be done so easily, as you only change the driver nothing needs to be change.
A simple yum erase php-mysqld and then yum install php-mysqlnd and a reboot will do it all and you don't need any backup nor any config change.
