Two new subscriptions were accidentally created instead of updating an existing one. Is it possible to reassign one of the new subscriptions to a different customer email address?
No, the email address associated with a subscription cannot be changed. It's recommended to cancel one of the duplicate subscriptions and create a new subscription for the intended customer.
Please ensure that you adjust the renewal date of the remaining subscription to prevent overlapping renewals. More details on updating subscriptions can be found here - https://support.boldcommerce.com/hc/en-us/articles/4404797982356-Subscription-Management-Merchant-Perspective.
