There is -- just install it over the top. Our goal with 5.x is to
make updates completely compatible, and so far we are pretty much

The UPGRADING doc shows you how to try it out first, in parallel, but
I know of nothing that would cause you a problem.

When we go from 5.x to 6.x, then you might worry. 8-)
