On Jouett, the upgrade was done as a single package.
The SPS-49 replaced the -40 in the 1980-81 baseline overhaul. At that same time the SLQ-32 was installed, replacing the WLR-1 suite. The SPS-48 was updated from 48C to 48D level, or something like that. And the CIWS and Harpoon were installed, replacing the 3"50cal guns. Also, Super RBOC replaced the earlier system, which I think was some sort of chaff delivered by a Zuni missile system. I started out as EW Officer in 1980, but didn't learn the details of the systems that were removed in 1980. I saw the crane take the parts off the ship. it looked like skinny torpedo tubes, but was for chaff.
That 1980-81 overhaul (which also upgraded missiles to SM-2 ER level and upgraded the fire control computer system), pretty much replaced every element of the combat systems onboard. I don't think the 5" gun had any modernization. I think the SQS-26 sonar was upgraded with a rubber window. This came to a bad situation in 1982 when the ship was steaming too fast into heavy seas and the rubber window failed, resulting in a short yard period in WestPac. Oops.
