I am using the tool Magic Mover to migrate Classic Attachments to Lightning files.
However, after conversion of an Attachment to a Lightning file, the Attachment's 'Name' field changes. The corresponding ContentVersion Id is appended before the 'Name' field of Attachment.
Attachment before conversion:
Attachment after conversion:
Is there a way to avoid this or is this the Standard default behavior? The requirement is to keep Attachment's fields as it is after conversion.
