Question

ensure that all the attachments from previous case are updated in new case. This new case will have all the URL links copied from
I need to attach the attachment URL of one case (ABC-12345) to a new case (ABC-12345). Here both the case numbers are the same (ABC-12345) so, once the case number matches the URL of attachments from first case will be updated to new case with the same case number.
Background:
Basically we are using email ingestion for case creation so we are able to extarct the email subject now. just need to transfer the attachments from one case to another.
