Office 365 update item permissions / Update item permissions

What it does

This action works with SharePoint list items, files, folders, metadata, content approval, or permissions. The key migration inputs are the target site, list or library, field mappings, and any dynamic item identifiers.

How Flow Migrator maps it

Flow Migrator maps this to Send an HTTP request to SharePoint (REST role assignments) using SharePoint. NAC Update item permissions is migrated to SharePoint REST calls for breaking/resetting inheritance, resolving principals, removing role assignments, and adding role assignments. Validate principals and permission levels after import. Flow Migrator has a direct or proven best-effort conversion path for this mapping.

Common migration issues

• Validate SharePoint site, list/library, content type, required fields, person fields, lookup fields, and attachment or file path behavior.
• Review HTTP method, URI, headers, authentication, retry behavior, premium licensing, and response parsing.
• Run a test instance and compare outputs against the original Nintex workflow before production migration.

Validation checklist

1. Open the generated flow and confirm the action card imported correctly.
2. Validate connection references and required settings before running the flow.
3. Test with representative source data from the original workflow.
4. Confirm site/list/library names and complex field mappings in the target tenant.
