Sometime I get emails from a customers in reply to a resolved case. They actually report a new problem but since they use reply, the email is being associated to the old case.
Is there a way to create a new case from an existing email or at least to re-parent the email to a new case I will manually create?

To allow this to happen, EmailMessage.ParentId would need to be modifiable.
Since the DML framework does not allow this, you will not be able to write Apex code to make this happen.
