There is no simple answer, as the characteristics of each link are unique,
thus the requirements for each potential upgrade are also unique.
Typically an engineering study will be done to determine what exactly is
required, and what the cost will be. It could be as simple and cheap as a
software license upgrade costing a few hundred dollars; to a complete
tear-down and re-build of the towers (to support much larger antennas, for
example), costing hundreds of thousands. It can even involve adding
additional sites as relays, potentially pushing the cost into the millions.
