Best way to replace a source file in the calibre database

Sometimes I have to modify a book file (say in PDF format) of a book record in calibre.

What's the best way to tell calibre to add the modified (PDF) book file and delete the old (PDF) file, without creating a new book record?

So far I have just replaced the file in the database's content directory, but I guess this is a dangerous approach...
