If you overwrite the schema for a tenant

[vague flax]

Overwriting the schema for a tenant does not automatically delete the existing data.

However, any changes in the schema might render some existing data obsolete or inconsistent with the new schema definition, so it's essential to manage schema updates carefully.

You can use DeleteAPI (https://docs.permify.co/api-reference/data/delete-data) or the Bundle APIs to remove data from the system permanently.

Also refer to following page: https://docs.permify.co/permify-overview/faqs#how-to-manage-schema-changes for the suggestion on how you can manage schema changes in our open source.
