I've been using Quicken 2000 Deluxe for over 25 years. I'd like to switch to a subscription for Quicken Classic. I'd like to KEEP my Quicken 2000 version with over 25 years of data but when I start to install Classic a warning that old versions of Quicken will be deleted. How can I KEEP Quicken 2000 and begin using Quicken Classic? Quicken support says it is not possible. Are they right?
