Migrating HTML Content SharePoint Error
Resolving page checkout conflicts during Sites migration.
Overview
Error Message
"Error migrating HTML content for page Test Page: The file '[...sharepoint.com/.../Test Page.aspx]' is checked out for editing by i:0#.f|membership|user@..."
Page Checkout Conflict
Root Cause
Page Checked Out for Editing
The issue arises when the migration tool attempts to transfer an ".aspx" file to the target SharePoint environment. Microsoft's system returns this error because the specific page file is currently locked — another user has the page open in editing mode.
What's Happening
- • SharePoint page is open in edit mode
- • The file is "checked out" to the editing user
- • Migration cannot overwrite or modify the file
- • Error is returned to prevent data conflicts
Solution
Steps to Resolve
Close All Editors
Close all active editor windows for the affected page(s) in SharePoint
Check In the Page (if needed)
If the page was checked out, check it back in via SharePoint's page library
Restart Migration
Restart the migration process - it should now complete successfully
