Not since V3R2 and V3R7+.  Starting with those releases, CHGPF has a keyword
SRCFILE() which makes the whole process automagic.  You just point it to the new
(ie changed) DDS and it remaps the data and takes care of the logicals too.  It
just needs exclusinve access to the file during the process.  It issues a
warning first if data could be lost -- e.g., a field is shortened or a field
name has been dropped.

I think I remember hearing there are some scenarios where the LF's aren't
completely handled automatically, but that has never been the case in my
experience.  The thing has been working like a charm for me for years now.
