Dear Sir,
CIC Spore has given you an e-mail address in their correspondences. You have been also given instruction in their correspondences of how to communicate them that in every correspondence from your end to CIC Spore that you must state your Application number and DOB along with your name.
It is better to attach the copy of your old passport along with the copy of your new passport and describe in detail that why you have submitted the new passport at VFS in your e-mail to them. You don't need to raise a Case, instead you directly send an e-mail to the e-mail address that they have sent you for sending correspondence if you require in any time during the process of your application.
This is my personal thoughts. Rest depends on your final own judgement.
Allahu Akber
