Hi @Gillian
From audit perspective, I would suggest you create a return document for original Sales order linked shipment, and take the document through the Return process. Here is the return process :

Create a new Sales order with correct customer and process the document further.
Ability to merge customer is not available at present, Here is the related feature request link:

Hope this helps,

Thanks for chiming in, @vkumar. There will be significant impacts on attached payments, shipments, and invoices.
As Vijay suggested, please create a new sales order and return the old one.
The above approach will work for Custom fields, other fields which does not have any impacts.
