The most common terms for changing cable network architectures are: new build, rebuild and upgrade.

Overbuild implies that the incumbent cable operator is about to get competition from another cable operator, maybe a telephone company. In essence, they are over building the incumbent with another network.

New build is just what it sounds like. A totally new network is being put in where none existed before.

Rebuild generally means that you are changing the basic structure of the network, say, from complete coax tree and branch to maybe 550 MHz HFC with fiber to the node.

Upgrade gets a little trickier, since some people use it interchangeably with rebuild. But more often, upgrade implies expanding the bandwidth of an existing network and the architecture and basic infrastructure stays the same. An example of an upgrade would be changing from 450 MHz HFC to 750 MHz HFC. Although amplifier spacing may need to change and the amplifiers themselves changed out, you are merely "upgrading" the system to 750, not changing its basic architecture. Sometimes an upgrade is as minimal as changing out the modules in the amplifiers, as in upgrading from 750 MHz to 860 MHz. No spacing changes, no cable changes, minimal headend changes.
