Think twice before going to ZCS 5.0.1
In hindsite I would sit tight for one or two more interations of 5 before I moved off of 4.5x.. unless there is a strong compelling reason. There are some real deal breaking user facing bugs in 5.0.1 some over a month old that really annoy many of our users. Look over the bug list for 5.0.1 and make sure none of these are deal breakers for you.... then read over the bug list again just to make sure. I went from 4.5.9 to 5.0.1 rather smoothly with a database integrity check no problem doing it just to make sure.
