Upgrade from 13.0.1 to latest

I inherited an install. I would like to upgrade and keep up to speed. To go from 13.0.1 to the latest. Is there a suggested path or is there issues to be aware of?

Hi from a post I made earlier saves me having to repeat: Upgeade Path: 13.4.1 to latest 14.2.0 - #2 by iwalker

Look at the docs for more info for your version information. The remainder of the steps is more or less the same.
