Well, it won't.  But as you won't be doing development under the old perl,
you won't need its user dpcumentation, i.e. the old perldoc.  The same goes 
for perlbug and perlcc (probably).  So you can replace those three with the 
new version.  Alternatively you might consider changing all the #! lines in
the old scripts to point at perl5.00404 instead of just perl.

Hope this clears things up.
