Do you know where your variables are?

Procedural code often tends to separate data and the processes applied to that data. OO tends to do the opposite.

Often procedural code is written in pseudo-OO style. I.e when you see a lot of subs with signatures like

sub do1($datastructure1, ..) sub do2($datastructure1, ..) sub do3($datastructure1, ..) sub do4($datastructure2, ..) sub do5($datastructure2, ..) sub do6($datastructure2, ..)
It is relatively easily to convert to OO code. You put all subs which work on same data structures in same classes and then you apply various refactorings(like this, this and this) to get more ideomatic OO code.
