We have tried upgrading PHP through Yum and also through other means. We do not know how to upgrade through Plesk itself as you need to register to Plesk and download their updates but the only thing we want to do is upgrade PHP 5.1 to PHP 5.3
Plesk breaks and becomes damaged if this is done through yum. So you need to becareful as we cannot keep affording to rebuild our server with our hosting company
The server is Redhat Linux Enterprise 5 64bit
Plesk version is 9
PHP is 5.1
we want PHP 5.3
You must have proven Plesk and PHP upgrade experience. Must be excellent with SSH and a server admin!
This needs to be done within the next 12 hours!!
