How to bulk migrate/transfer documents in one document type to another document type in EDM

[ayushidekate]

What is ServiceNow's best practice? Do they advise migrating documents from 1 document type to another?
So that we can retire document types that are no longer needed and unify the list of all document types
is it possible OOTB to migrate document types from one document type to another?

Hi @ayushidekate 
ServiceNow doesn’t typically recommend migrating documents between different document types unless necessary, as each document type often serves a specific purpose and is linked to certain tables. While there’s no out-of-the-box (OOTB) feature to directly migrate documents from one type to another. 
If you try to do it with custom development like writing script to copy doc from one type to another or used data transformation it can have some unintended consequences in you system

Is there any documentation which states that the ServiceNow Documentation that can explain this?
