We just updated from PHP 5.4 to 5.5 with WHM. It took the server about 10 minutes to compile, and it went off without any problems. Thanks be to the nerd gods!
We had a worry about a few WordPress installs (WordPress 4.3.1) and an old CodeIgniter codebase – but all went well.
Why the upgrade?
We wanted to take advantage of PHP namespaces. But as an added bonus, we noticed a nice speed boost in PHP – even our old apps are running much zippier now.
… On top of that, apparently PHP 5.5 uses 50% less memory than PHP 5.4.
So far so good.

We just upgraded our servers to Apache 2.4.9 (and PHP 5.4.29) so that we could use the Laravel PHP framework.
The upgrade was pretty flawless, save two minor issues: one with a WordPress plugin and the other was with a PHP.ini setting that was no longer supported in Apache 2.4.9.
… This caused CodeIgniter to show a 500 internal sever error. CodeIgniter error handling stinks. That alone is reason enough to dump CodeIgniter.
Apache 2.4.9 is fast!
As an added bonus, we were pleasantly surprised to find that Apache 2.4.9 is significantly faster than what we had been running – Apache 2.2.27.
It’s best to keep your server software up-to-date to take advantage of performance improvements and security fixes. If you let your software get too out of date, the eventual upgrade could be a nightmare as radical changes to software, is more likely to break things than minor upgrades.
