Isn't this the same as GCI? Russian fighters have had dedicated datalinks for target updates from ground radar for ages.

GCI is a wrong terminology. It's more like a guy telling the pilot where to go and where is the target. It's slow, even with datalink directly transmitting target data, it's not as comprehensive.

IACCS is more like the pilot gets a very high bandwidth feed of everything happening around his airspace. The network has already vetted and identified the target. You can use it to fire weapons. Or the network can use your sensors to fire a ground-based weapon.
Ideally, the level of integration should be so high that it shouldn't matter which radar is tracking the target and which weapon system is engaging it.

For example, you get a target track from Rafale but it's engaged by an S-400. I'm not really sure if IACCS is there or not. Maybe it's definitely there for some weapons like MRSAM, Akash-NG.

Spyder, older Kub, S125, Osa all units integrated?

They all get IACCS input.

Some units likely get the threat picture only, while that allows them to maintain RF silence, the missiles themselves do not necessary datalinks to let the system engage with IACCS input only.

Systems like MRSAM, Akash-NG have two-way datalinks. Therefore, it's likely they can engage solely based on IACCS inputs.

Akash gets its midcourse updates from the command link built into the radar itself, so even with onboard seeker, I don't think the option to engage targets with IACCS input alone is there.
