The move away from CDMA happened with LTE. LTE required a complete network upgrade to add in the eNodeBs to supplement the BTS (basestations) from the CDMA world.
5G (3gpp rev 15 or newer) does require new hardware but a lot of networks have been planning for this. Sprint has been rolling out new MIMO capable antennas for use with 5g. Verizon similarly has been future proofing before the standard was finished. There will be new equipment required no matter what though. Especially with Verizon pushing millimeter in cities.
