Conversion partial code from Studio5000 to TIA Potal

Hi there,

Recently we have a client who has code written in studio5000 using 1769-L30ER PLC. Most the codes written using AOI. Some of these AOI used to configure hardware of third party like reading/writing Beckhoff Ethernet IO Chassis.  Client requires to move the AOI to Open Controller CPU 1515SP PC2 Using TIA PORTAL.

My question, how can we establish communication between those controllers? How can data exchange between those controllers?

By moving AOI to diffrent platform, how can studio5000 points to those AOI in TIA PORTAL? Is there any suggestion on how tags/ parameters transfer in this case?

Thanks, and appreciate your response in advance.
