Old STBs and the newer DTA (Digital Terminal Adapters) have decryption built in. CableCards were mandated for cable STBs & DVRs by the FCC to enable customer provided equipment (most notably Tivos).
I don't know for sure, but I suspect that simply taking the CableCard out of the old Tivo an putting it into the new unit will work fine. The card's ID number is registered with Verizon so it should work no matter what model Tivo the OP has. Worth a try. If that doesn't work then call Verizon and they likely would be able to talk the OP through it.
Cable cards have EVERYTHING to do with copy protection. For about 9 years under FCC mandate, companies have been required to use seperarable security, and VZ boxes contain cable cards under that mandate. The DTA's, without seperable security are used under an exemption from the FCC.
There are 3 levels of signals under VZ's implementation. The signal is sent via fiber to the ONT. It is then converted to RF using standard QAM frequencies by the ONT and sent over the coax, in effect making each ONT into a mini-headend in cable analogy. Broadcast channels are sent by the ONT in the clear (unencrypted) and can be viewed on any digital-capable tv with a QAM tuner. All channels other than HBO, Cinemax and 131 are encrypted, but not copy protected. The cable card, which receives authorization on an OOB channel decrypts channels that are permitted.
As for copy protection, the cable card standard uses a "CCI byte", that is set for each channel. It permits copy freely, copy once, or no copy. This flag is used by some cable companies to copy protect all channels other than broadcast so they cannot be transferred from machine to machine, or using a TiVo Stream, sent out of the home. Verizon didn't set this on any channel until HBO required it on their content.
The cable card is authorized to decrypt the non protected channels, but to receive the protected ones, it must be paired using a host id unique to the device, as well as a generated by the host data id that changes with each cable card.
In short, on FIOS, the card can be moved to a new TiVo and since the OOB EMM's have it authorized, receive all non copy protected channels. It must be re-paired, using the new host and data id's to receive copy protected channels.
