Common Migration Error Questions

How do I fix error 429 "Too Many Requests" during migration?

Error 429 indicates Microsoft Graph API throttling. Reduce the number of concurrent migrations, enable automatic retry in Cloudiway settings, or schedule migrations during off-peak hours. Cloudiway automatically handles throttling with exponential backoff.

Why am I getting "Access Denied" errors during migration?

Access Denied errors typically occur due to missing permissions on the EntraID application or service account. Verify that all required API permissions are granted and admin consent has been provided. Check the specific article for your migration type.

How do I resolve authentication errors (401 Unauthorized)?

Error 401 usually indicates expired credentials or incorrect authentication configuration. Verify your connector credentials, check that certificates haven't expired, and ensure the service account has the required licenses and permissions.

What should I do if migrated files are not visible in Teams?

Files may not appear immediately due to indexing delays. Wait 15-30 minutes for SharePoint to index the files. If they still don't appear, check folder permissions and ensure the files were migrated to the correct document library.
