I currently have a genie with esata 3TB hard drive connected. Have upgrade schedule to get Genie 2 along with 4k receivers. Is it possible to connect my current external drive into the genie 2 and not lose recording or other settings? If not is it possible to connect to any older receivers (have couple not sure model numbers) and will it boot and allow to access recordings and settings? In past prior to ATT during upgrades Directv would allow me to keep current receiver, deactivate, then ship back at a later date. ATT is now allowing this.
