What happens with Sales orders and AR documents upon using duplicate customer merge in CDM?

Summary:What happens with Sales orders and AR documents upon using duplicate customer merge in CDM?

Content (required): In document 2708893.1 it is explained how you can merge multiple customers, multiple accounts, multiple sites using CDM.

In the 'Implementing Customer Data Management (CDM) for CX Sales and B2B Service' it is specified that the merge scope for Duplicate Resolution is "All customer relationship management related areas: Merges Customer Data Management foundation entities and transfers CRM transactional data, such as Opportunities, Activities, or Service Requests, from duplicate records to the master record. "

 

I am looking to understand the impact on Sales orders and AR documents (invoices, credit memo's,...) when using CDM to merge duplicate parties, accounts and sites? I.e. what will happen to the sales orders, invoices attached to an account/site which is subject to merger?
