Upgrading from 64-bit PHP 5.04

I have a dedicated hosting server and it has 64-bit FC4 installed with 64-bit PHP 5.04. I have found many apps that won't work with the 64-bit version of PHP5.04 (seems to be a little buggy) and would like to upgrade. I have retrieved the RPM's for the 64-bit PHP 5.16, the question is how do I go about upgrading without having downtime on the server since it is a live server hosting many clients? RPM -U and then restart Apache? I am using PHP as a loadable module in Apache so it is not compiled into it. Also I have the following modules installed as well: php-bcmath php-dba php-devel php-gd php-imap php-mbstring php-mysql php-ncurses php-soap php-xml php-xmlrpc do I have to upgrade these as well? -- Scott Ackerman 1212 Baker Street Fort Collins, Colorado 80524 970-231-9035 Fax 888-290-2131 "Every improvement in the standard of work men do is followed swiftly and inevitably by an improvement in the men who do it" - William Morris
