PHP 5.3.4 to 5.3.13 update. How?



I had some old VPS host (created 0.5 - 1 years ago) configured to use PHP 5.2. Today I reseted the host to it’s default Dreamhost configuration and switched it to PHP 5.3 FastCGI. I created a php webpage with phpinfo() and it shows me PHP version 5.3.4.
Recently I created from scratch new VPS and the version of PHP there is 5.3.13.

My question is how could I tune my old VPS server to have newer 5.3.13 php version?

Is the only way is to compile custom 5.3.X installation (this is diffucult and error-prone) / throw away this host and create the new one where the last 5.3.X version will be already bundled (I don’t like this either, as this will require data copying to new host)? Or there is some easier way?

Please suggest.

I searched through wiki/google/forum - still no luck, everywhere is described 5.2 -> 5.3 upgrade, not 5.3.X -> 5.3.Y.
