Permission Missing
Cause 1: File Migration Issue
Missing OneDrive Permissions
The migration account lacks permissions to access the user's OneDrive. This commonly occurs when the OneDrive hasn't been provisioned or when permissions haven't been configured for the migration account.
Solution for File Migration
Run the preprocessing task from the user list. This automatically:
- • Provisions the OneDrive profile if not already created
- • Sets necessary permissions for the migration account
- • Validates access before starting migration
Cause 2: Sites Migration Issue
Missing Site Collection Admin Rights
The SharePoint connector's migration account doesn't have sufficient permissions for the target SharePoint site. The account needs to be a Site Collection Administrator.
Solution for Sites Migration
- 1. Go to SharePoint Admin Center or the target site
- 2. Navigate to Site Settings → Site Collection Administrators
- 3. Add your migration account as a Site Collection Administrator
- 4. Wait for changes to propagate (may take a few minutes)
- 5. Restart the migration
