Do you mean literally putting new deck boards on the existing boards,
as is done with asphalt shingles?
Or do you mean rip the decking off, and replace it, using the existing

The first is a bad idea.  The second is potentially okay; it depends
on the structure being in good shape (it often is), and being suitable
for the new material (as others have noted, the composite stuff isn't
as strong, and requires more support), and there not having been some
change in the local code that requires change or replacement.
