Hi there,
i found a possibility to update from PHP 5.3 to PHP 5.4 (https://launchpad.net/~ondrej/+archive/php5)
My questions are:
Short information:
I am using a file upload script. If I use PHP version 5.4 or newer there will be a upload progress bar. It's only a "nice to have" feature so I wanted to ask if it's possible at ... no risk?? 
Hello,
i-MSCP is not full ready for PHP-5.4. I would recommend you to wait little.
Thank you for the information.
Is there already a request to get I-MSCP 5.4 ready?
Re ;
No. You can create a ticket if you want.
I cannot recommand using 5.4. I did so for testing purposes on a gentoo-machine and had trouble with some popular applications (like squirrelmail for example). Is there anything in 5.4 that you need especially or is it only about having the newest version? 
New does not always mean its better than the older version. I get very paranoid when something 'new' comes out as there is normally more bugs than the old version (not talking about i-mscp )
so many popular applications will not work with 5.4 or will be heavily deprecated. give it time first
