Pls see attached photo of existing cupboard hinges, which are 25 years old, working well, but not soft-close.

It would be nice to replace these hinges with a soft-close hinge. Is it a simple matter of removing the old and replacing with a new one, or do extra holes usually need to be drilled in the cupboard?
Also, are cutlery draws able to be "easily" retrofitted with a soft-close mechanism?
Thankyou.
