Change display name with CLI without modifying the client name”

Hi

I found the previous conversation related to the same topic “ Change display name with CLI without modifying the client name”

Using the XML 

<App_SetClientPropertiesRequest> <association> <entity> <clientName></clientName> </entity> </association> <clientProperties> <client> <clientEntity> <clientName></clientName> <displayName></displayName> </clientEntity> </client> </clientProperties> </App_SetClientPropertiesRequest>

Command:

qoperation execute -af update_client_name_template.xml -entity/clientName $client -client/clientEntity/displayname $new_displayName updateNameChangeOnlyInDBOnFailure=1

We have clients registered with short name, I want the clients display name to be updated with FQDN without changing the short client names. 

I tried the above XML and command and found the error. Could someone help with pointing correct information.

Error

execute: Error 0x911: Failed to process request due to invalid entity information.Invalid clientId for clientNamerxxxx.hosting.com].
