Going from 3 to 5 can break a number of important things. For example, join
syntax semantics and precedence rules have changed since 3, and it is
certainly possible this could break your code in important and dramatic

You should plan on spending time checking out all the SQL. Just as
important, your MySQL host should really provide a 5.x playground for you to
check your app out in for at least several weeks prior to the upgrade. Just
waking up one morning with the database "upgraded" is almost surely going to
be a mess.
Yeah - I think the playground is unlikely to happen. They certainly
haven't said anything about providing such a facility.
What I'm banking on is that my own usage of MySQL so far (I'm
learning, I'm learning!) is sufficiently primitive that it won't be
upset too much by the change!
