CDA (ARA) folders cannot be renamed.
When trying to rename CDA folders with REST API, the following error is present:
Error: ‘The folder ‘FOLDER1’ is already used by X objects and cannot be changed.’
Release : 12.1, 12.2, 12.3
Component : RELEASE MANAGER/CDA
CDA folders have different configuration rather than Automation Engine folders.
The referred documentation describes the renaming of AE-objects whereas the REST-interface can be used to rename CDA-permission folders:
AE folders: https://docs.automic.com/documentation/webhelp/english/ALL/components/DOCU/12.2/CDA Guides/Default.htm#AWA/Objects/obj_renaming.htm
CDA folders: https://docs.automic.com/documentation/webhelp/english/ALL/components/DOCU/12.2/REST%2BAPI/Continuous.Delivery.Automation/index.html?overrideUrls=./swagger.json,../Automation.Engine/swagger.json,../Analytics/swagger.json#/Folder/Folder_Get
Renaming a CDA-permission folder works only if no CDA-object is assigned to this folder because access permission to the AE-object is based on their names. Therefore, renaming a CDA-permission folder requires to rename all effected AE-object (AE-workflows, AE-login objects, etc.) and adopt all users & groups AE-authorizations.
