You'll want to set up a test installation and do some compatibility testing --- it seems quite likely to me that you'll find a few things that need adjustment in your client apps and/or SQL schema.

Egad, man. 7.2 was abandoned years ago because of unfixable bugs... As a first approximation, you could suppose that every major bug we've fixed in 7.3 since 7.3.10 is also in 7.2. And should I point out that several data-loss bugs were fixed post-7.2.1 before we abandoned that branch? If there's any valuable data in that DB, to still be running 7.2.1 is lawsuit-worthy negligence.
