You should go right to some version of 7.4. 7.4.1 should be out soon.
7.4 has a number of performance and maintainability features that you
don't want to miss. Going to 7.3 will be ablut as hard as going to 7.4,
so you might as well get the extra benefit.

Schemas are new in 7.3 and that might cause you to worry about them.
You can read through the release notes for 7.3 and 7.4 to look for
changes that might cause you problems.
