two ds 160 forms

I had filled a Ds-160 form, paid and scheduled an appointment. I however changed my intended date of arrival and so i have filled a second ds-160 form. i now have two forms. should i bring both? The appointment is under details of the old form. will this be a problem?

Intended date of arrival shouldn’t matter as long as it after start of 797. Still if you want to change it, carry both DS forms to the interview. There you can ask it to be switched to new DS form (there is a counter inside consulate where they go over DS form w/ you), or just ask the person to update it in existing DS form.
