Files which have no checked in version cannot be migrated (4375882)

When migrating files in SharePoint, you might encounter several warnings in the logs, including:

• "List Site Pages includes 'x' files which have no checked-in version. These files cannot be migrated."
• "An issue occurred while processing web parts."
• "Unable to process the following parts 'xyz' (File Not Found.)"

To resolve this issue, follow these steps as a SharePoint Site Admin:

1. Go to the Document Library Settings:

   • Navigate to your source document library settings.

2. Manage Files with No Checked-In Version:

   • Click on the “Manage files which have no checked-in version” link located under the Permissions and Management group.

3. Select Checked-Out Files:

   • Under “Files checked out to others:”, check the boxes next to the files you want to take ownership of.

4. Take Ownership:

   • Click on “Take Ownership of Selection” and confirm the prompt “Are you sure you want to take ownership of [file name]?”.

5. Check In the Files:

   • Now that you have ownership, go back to the document library and check in the files.

6. Re-Run the Migration:

   • Once all necessary files are checked in, re-run the migration process.

By taking these steps, you'll ensure that all files are properly migrated without any issues.
