Confusion over what version of PHP I will have after upgrade

[SacAutos]

I'm running Plesk 10.4.4 on CentOS 5.8 and am considering upgrading to Plesk 11. However, I have a number of websites that I am hosting that actually require that I stay on PHP 5.1.6. My understanding is that the version of PHP is a function of my operating system and not Plesk. (Having said that, I know that I can go to PHP 5.3 if I install that via the panel as an option.)

When I read the release notes for Plesk 11, it states:

"Upgrade of supplied components. Panel 11.0 includes the following components:

[...]
PHP 5.3.10 for customer websites
PHP 5.3.10 for the Panel web interface
[...]
"

So this is confusing me. Am I going to get 5.3 for my customer sites as part of the update or is this referring to the version of PHP that is the option? If I update and I wind up with 5.3 for my customer sites, that is a disaster as the sites will stop functioning.

Can someone please clarify?

Yes, as a default upgrade of plesk php 5.3 will be installed and that could break your customers websites since they require a much lower version.

However, you can downgrade it anytime with the command: yum downgrade php*

Very helpful info. Here's a follow-up

Another factor that I neglected to mention is that I also have php-mcrypt installed. Is that going to disappear, prevent the update or be included in the new PHP version? Anybody know? This is another important factor to consider when or if I update.

I somehow thought I responded to this but suprisingly I see now response from me

Anyways, I highly doubt if an upgrade would remove your php-mcrypt already installed..
But if it did, then installing it back would be as simple as running the command:

yum install php-mcrypt

I'm not so sure

Thanks again for trying to help. The reason why I'm asking is that php-mcrypt and the PHP 5.3 add-on via Plesk 10.4 are mutually exclusive. I was curious if this had been resolved for Plesk 11. Unfortunately I don't have a test server at the moment that I can use to do a trial install to find out for myself. Nobody else has this concern?

Don't worry Dave, I have used my server to drive test this ...
I have both PHP Version 5.3.14 and php-mcrypt all running without any problems.

You may see below for the phpinfo() data:
