We would first need to refund the difference in payment between these two levels.
  1. Go to Sales > Refunds.
  2. Search for the order number to bring up this transaction.
  3. Under the Refund column, change the monetary amount to reflect the difference in cost.
  4. Adjust the payment method as necessary, and then click Refund.
  5. When it asks if you want to Cancel the membership, click No.
Once the refund is complete, we can change the level from the membership record.

  2. Click Other Tasks at the top.
  3. Click Edit Membership Details.
  4. Click the dropdown box for Level, and adjust this to the member's new level.
  5. Click Save.
