Bolt upgrade

Last year I bought a used OTA Romeo for $230 with lifetime and upgraded the hard drive to 2tb.
My account lists I have a 1tb Romeo. Im wondering if they even know I upgraded the HD?

Today I bought a renewed Bolt with 500gb for $149 and transferred my broken series 3 lifetime for $99. I will get it next week.

Questions: If I upgrade my new Bolt to a 1 or 2tb drive will it void my warranty or will Tivo know I did it??
Is the upgrade procedure the same as the Romeo except its a 2-1/2" drive....
