I have a server turning on Plesk 10.4.4 and I want to upgrade it to 11.0.9.

When I use the online upgrade tool, I have this warning:

Parallels Panel pre-upgrade check... WARNING: You have a mixed set of 'php' and 'php53' packages installed. Installation or upgrade may fail or produce unexpected results. To resolve this issue run "sed -i.bak -e '/^\s*skip-bdb\s*$/d' /etc/my.cnf ; yum update 'php*' 'mysql*'". PHP Warning: Directive 'safe_mode' is deprecated in PHP 5.3 and greater in Unknown on line 0

I have run the code in ssh, but nothing changes.

I have already searched all package names with "php", and I have this list:

After verification in the Plesk file: panel_preupgrade_checker.php

I think the warning is due to these lines:

(from : panel_preupgrade_checker.php)
foreach ($packages as $package) {
       $name = $package['name'];
       $hasPhp5  |= ($name == 'php' || strpos($name, 'php-') === 0);
       $hasPhp53 |= (strpos($name, 'php53') === 0);
    }

Now, I think the problem is just due to the names of theses packages:

php-common.i386                      5.3.13-5.el5.art                  installed
php-pear.noarch                      1:1.4.9-8.el5                     installed

Can you help me to resolve this situation?
