I just had this problem. After getting the new 722k, upon bootup, the new 722k brought up the configuration/setup screens. After the new 722k was working, I pulled the plug, removed the new hard drive and put in the hard drive from the old 722k. Because activating the new 722k had automatically de-activated the old 722k, I had to call Dish to have them reactivate the old device. But that was only necessary so that I could view the Timers and Favorites (the receiver must be "connected" to access those screens). After that, I rebooted and everything appeared fine. I then used my camera phone to take screen shots of all of the old settings, including Timers, Favorite channels, etc. Finally, I connected an External Hard Drive (EHD) and transferred all of my recorded shows from the old hard drive to the EHD. I powered down, swapped the drives again, connected the EHD and transferred all of my shows onto the new internal drive. I'm about to recreate my Timers & Favorites and other settings using the screenshots.
