Is it possible to issue a refund for the upgraded subscription and then request a refund for the pre-upgrade subscription?

Hi, I have a question about Apple subscriptions.

It is my understanding that when a user upgrades, the subscription prior to the upgrade is already prorated and partially refunded.

Is it possible to issue a refund for the upgraded subscription and then request a refund for the pre-upgrade subscription?

The server notifications I received were as follows

  1. purchase A
  2. upgrade A -> B
    • A would have already been prorated and partially refunded
  3. refund B
    • Has a revocationReason / revocationDate
  4. expired B
  5. refund A - should have already been prorated and partially refunded, but if the user requests another refund, will it be given?
  • no revocationReason / revocationDate
    • My guess is no because it's already in revoke status.
  1. refund reversed A
  • This may not be present
Is it possible to issue a refund for the upgraded subscription and then request a refund for the pre-upgrade subscription?
