Migrating DLP Policies from one tenant to other
Has anyone successfully migrated DLP policies from a dev tenant (like contoso.onmicrosoft.com) to a production tenant (paid license with custom domain) in Microsoft Purview without third-party tools? We're open to using PowerShell, Power Automate, or other Microsoft technologies—such as exporting policies via PowerShell cmdlets from the source tenant, then importing/recreating them in the target tenant using the Microsoft Purview compliance portal or Security & Compliance PowerShell module. Details: The dev tenant has several active DLP policies across Exchange, Teams, and endpoints that we need to replicate exactly in prod, including sensitive info types, actions, and conditions. Is there a built-in export/import feature, a sample script, or Power Automate flow for cross-tenant migration? Any gotchas with licensing or tenant-specific configs?
