Can I migrate my Seal Subscription subscribers to a new store?

You should be able to migrate your Seal Subscriptions from an old store to a new one with the help of our Quick Checkout Links feature.
You could set up a new subscription rule in your new store, generate a quick checkout link with our Quick Checkout Wizard and then paste the link into the "Pause confirmation" or "Cancellation confirmation" automated email template in your old store.

By doing that, you could cancel or pause the subscription on your old store and they would receive the cancellation/pause email informing them of the reason and providing them with a link to the new subscription.

However, keep in mind that by sending the quick checkout links to your customers, there is no guarantee that they will resubscribe.
