Alberto,
I confirmed with the BU that there's no CTS 3000 -> TX 9000 upgrade. The CTS-TX9K-DEV-KIT is for lab testing so you don't need a chassis and full set of displays. You might need to speak with your sales people if they were buying that to upgrade a production room, since that's not the intended purpose. Unsure if this is a custom solution of some kind.
