XF 1.5 Updating from 1.5.5 to Latest?

I'm certain this question has been asked before but here goes.

My Current version of Xenforo is 1.5.5 and after rebuilding the server from the ground up with the latest and greatest versions of Apache, MySQL, PHP etc... I figured it was about time to update Xenforo itself to the latest and greatest version (1.5.14 if I'm not mistaken?)

Can I do this as a single jump or do I need to install all the sub-versions in order?

Thanks in advance...
