You could *probably* do this without error - but check through the 
changelog for NOTE INCOMPATIBLE warnings.  IIRC there are a few things 
that changed incompatibly somewhere in that range.

You also tend to miss out on new features in the new default 
mimedefang-filter;  I usually at least scan through quickly side-by-side 
with my existing filter and see what's new, and compare that with what I 
changed myself.
