Sharepoint 2013 to SPO with SPMT issues: Fatal error, Could not retrieve file's metadata.


We are trying to migrate from SharePoint 2013 to SPO using SPMT but we are having problems.

In some cases the scan is done but the tool does not migrate any file and in the report it does not show any error.

We have changed the destination folder and the tool works fine but when migrating another folder it stops working. That is, the tool migrates folders randomly and we don't know why.
We have already checked the source and destination folders and there is no problem, we have administrator access.

We have also had these errors in the reports.
Failed to Read the file: Could not retrieve file's metadata
Errors or timeout for Server Processing the file: Job Fatal Error.
Errors or timeout for Server Processing the file. Fail to look up folder name. The item may exist in other list or site in the same site collection. Or the item is in the recycle bin.

I would like to know if you can help me or give me some advice to migrate correctly.

    Hi @Anonymous , welcome to Q&A forum!

    Usually SPMT will not randomly migrate files, but will migrate content according to the plan you set. Some migrations were successful, and some were unsuccessful for some reasons. Approximately how many files have this issue? Are there any similarities among these files?

    Here is an official article about SPMT troubleshooting, you can do a simple check first:
