Need to update DS 160 Form

Hi Everyone,
I had scheduled visa appointment in old portal last year and there was a way to modify the DS 160 form number in visa stamping portal. And due to some life events, I wasn’t able to submit the DS160 which was used for scheduling the appointment at that time.
Now the details have been moved to new portal and I have appointment rescheduled to Jan. But the old DS160 form number is still tagged to that and there is no way to change it. Now for the appointment, I don’t have the old DS 160 confirmation page, however, I have filled the new Ds160 form and would like to know if I can take this new confirmation to the appointment? Could someone please help me here?
