A unified data governance solution that helps manage, protect, and discover data across your organization
Hi Ipshita,
Thankyou for reaching microsoft Q&A!
In the new Microsoft Purview experience, the service operates at a tenant level, so multiple instances like Classic Purview are no longer supported. For testing, the recommended approach is to use domains and collections to create logical separation within the same environment. You can create a dedicated Dev/Test domain, build separate collection hierarchies, and apply scoped RBAC roles so testing activities do not impact production assets. Register non-production data sources and validate scans, classifications, and policies within these isolated collections. If complete isolation is required, the supported option is to use a separate non-production tenant rather than requesting additional Purview instances.
