Correct way of updating PHP/MySQL on a running Plesk 11.5 server?

Question

I need to update my server to PHP 5.5 and MySQL 5.6, currently running Plesk 11.5 (CentOS x64). I've added the following repositories to YUM:

rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm

And I can run yum update to globally update the system.

Should I need special commands or just merge .rpmnew files into existing ones (i.e. php.ini and my.cnf)?

AFAIK Plesk 11.5 does not support MySQL 5.6 officially because the STRICT_TRANS_TABLES SQL flag enable by default. Can I simply remove the flag from my.cnf until Plesk 12?

Just for experiment, I've tried to upgrade PHP and MySQL to this version.

I've only get issue with ODBC connector:

ODBC error #01000: [unixODBC][Driver Manager]Can't open lib '/usr/lib64/libmyodbc5.so' : file not found


ODBC error #08S01: [unixODBC][MySQL][ODBC 5.3(w) Driver]Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

At installing Plesk registers following DSN in /etc/odbcinst.ini

[MySQL]
Description             = MySQL driver for Plesk
Driver          = /usr/lib64/libmyodbc5.so
Setup           =
FileUsage               = 1
Driver64                = /usr/lib64/libmyodbc5.so
Setup64         =
UsageCount              = 1

After installing MySQL 5.6 there is no more file /usr/lib64/libmyodbc5.so, because it's provided by mysql-connector-odbc-5.1.5r1144-7 which is not installed any more.

But there is /usr/lib64/libmyodbc5a.so and /usr/lib64/libmyodbc5w.so (from new 5.6 connectors).

I've replaced in /usr/lib64/libmyodbc5.so to /usr/lib64/libmyodbc5a.so in /etc/odbcinst.ini.

And as I can't get how to configure socket for this driver i've add symlink:

ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock

After that I've see that plesk mostly runs fine even with STRICT_TRANS_TABLES.

To keep link after server restart add following string in the beginning of /etc/init.d/mysqld:

if [ ! -L /tmp/mysql.sock ]; then  ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock ; fi
