Transferring a Relationship

Hello everyone,

I am aware that through the GroupMember endpoint, relationships can be added and edited; however, it does not seem that a relationship can be moved from one group to another. I attempted to do this by changing the Parent Identity Element while leaving the GroupMemberDetailIds in place since this is the key-value pair that lets the system know that the POST is an update rather than a new creation; however, I was not successful. Ultimately, what I am attempting to accomplish is an update to the ID field in the Relationship table. I want to maintain all of the metadata related to the table row. I do not want to delete and add a new relationship. Looking forward to hearing if this is possible.

Thanks,
Korey
