If you already have the Chase Sapphire Preferred card, you may be able to upgrade to the Chase Sapphire Reserve card. You should call Chase and speak to a representative to see if you are eligible to upgrade. Note, you can't earn a sign-up bonus if you choose to upgrade. If you want to try to qualify for the sign-up bonus, make sure enough time has passed, then close your Sapphire Preferred account or downgrade to a different type of Chase card, and apply for the Chase Sapphire Reserve card.
