When attempting to migrate a file, one of the following message is displayed:
- SharePoint returns an error after transferring the file. You should retry to transfer this document again.
- Could not retrieve file size information from SharePoint.
- Could not retrieve the file correctly because SharePoint returned an empty file. This may be caused by a corrupted file.
You can retry to migrate your file again at a later time. If you still encounter this issue, try to avoid migrating multiple big files at the same time.
To check if the source file is corrupted, download a local copy of the file with your browser and/or SharePoint Designer. If neither of these works, this most likely means that the file is corrupted in SharePoint and cannot be retrieved by Sharegate.
