Rename existing Data Source or Create New Data Source Pointing to existing Records cause field UUID Change

Question

Hi Appian Community, 
 we have one application for which development is completed and planning to migrate it to new UAT instances, 
 Already have created many records configuring data source in admin console by name like " jdbc/ApnDev001 " 
 have plan to create new data source with the name of " jdbc/Appname " in new UAT instance, 
 while doing to observed that we need to change data source for existing records causing field UUID get changed, and this leads to huge changes at application level wherever we have used these records. 
 Is there any way we could fix this issue (rename or create new data source) without major changes. 
 
 any form of guidance would be welcomed, Please help. 
 
 Thanks, 
 Shree Krishna tiwari

I would recommend creating data sources with Connected Systems in lieu of the admin console to avoid this issue. 
 Also in 25.1, you can change the Data Source without breaking field references. 
 https://docs.appian.com/suite/help/25.1/Appian_Release_Notes.html#seamlessly-remap-record-fields-to-different-source-fields 
 I would recommend doing this before migrating.
