The Migration of subscribers can be done within PushOwl considering both the subdomains have PushOwl installed on them.
Changing domains in PushOwl comes with the limitation that subscribers are domain-specific, meaning they are tied to the original domain where they subscribed.
Migration can be done with subscribers from the old store to the new store only if the domain is the same because permission for web push notifications is granted on a domain level.
Domain-level permissions are imposed for security reasons, which is why migration between completely different root domains is not technically feasible.
Best Practice for Subscriber Migration within PushOwl
Here's how you go about migrating your web push subscribers from one subdomain to another within PushOwl.
1) Send an email from the store owner's email address to support@pushowl.com, requesting the migration.
2) The email should clearly state the old subdomain (from which subscribers have to be exported) and the new subdomain (to which subscribers have to be imported).
3)After we receive the email, we will raise a ticket to the tech team to complete the migration.
Sometimes, a merchant may also decide to create another storefront for regional and international customers.
Example:
A Norwegian brand has two stores, one for Norwegian customers and one for international customers.
https://mycoolstore.no - For Norwegian customers
https://mycoolstore.com - For international customers
In this case also, since the store domains are different, we can not migrate subscribers from one store to another store.
As a best practice, merchants can plan a re-acquisition campaign to retain subscribers or direct them to re-subscribe to the new domain using PushOwl campaigns.
