Is that possible to change Two-way sync unique identifier field?

Hello,

We have developed Two -way sync connector for one of our client, the solution is working pretty fine so far but now customer wants some modification into existing automation which I have analysed by our side but it seems like we can not handle the record if unique identifier fields have updated!

Can you please let us know is there any possibility to handle below requirements?

Let’s say a record with primary email abc@gmail.com in DP and 360Alumni is syncing. If I change the primary email in 360Alumni to deg@360Aluni.com, what will happen in DP to the record with email abc@gmail.com?

Thanks,
Dhruvit

Two-way sync uses the specified item ids to link records:

The values used to identify records cannot be changed in the systems, otherwise the 2ws linkages stored in the database would become incorrect. Normally these would be unique record ids that can never change anyway.
