Ludwig beat me to it (I'm having WiFi issues). My full "analysis" from the latest Configuration program is:
Confirmed in the latest version of the Configuration program (it's not explicitly in the 808v6 connection info in the properties tab, but can be inferred from 818v2/v3 and 808v5 connection info):
IA04 analogue input card in 818v3/808v6 unchanged.
OA28 analogue output card in 818v3/808v6 replaced by OA25.
ID29 and IE48 digital input cards replaced by single IE58 card.
OE38 digital output card unchanged.
