Update EmailMessage RelatedToId

I want to relate an outbound email message to a different Opportunity. EmailMessage.RelatedToId holds the Id of the Opportunity for which it's related to. I attempted to simply change the RelatedToId on the EmailMessage using Execute Anonymous but it doesn't work. Getting error "System.SObjectException: Field is not writeable: EmailMessage.RelatedToId".
EmailMessage msg=[SELECT Id, RelatedToId FROM EmailMessage WHERE Id = '02so000000I7rXuAAJ'];
Update msg;

Is there another method of updating this field?
