Migration manager giving the Scan File Failure errors "Could not retrieve file's metadata" and "The parent folder was not migrated" on at least 50% of all files when attempting to migrate fileshare to OneDrive

Question

Im currently migration an On-Premise fileshare to OneDrive using migration manager. My agent is installed on a server in the same forest as the fileshare and has 105.02 GB available storage space. (Ive requested a VM with over 150GB to be added as an agent) The largest user I'm trying to scan has 67GB, the total storage of the 3 users in the pilot is 91GB.

When I scan the users Im getting the Scan File Failure errors "Could not retrieve file's metadata" and "The parent folder was not migrated" on at least 50% of all files and folders for each user.

I was wondering if you could help.

Thanks,

This issue may be caused by the Temporary storage on the local computer is too low.

In %appData%\Microsoft (most likely on C-Drive), Migration manager creates a folder named "MigrationToolStorage" to save the blobs or temporary data whilst it scans & uploads etc.

You could try to run following commands to create a link to a different storage with more space.

cd %appdata%\Microsoft
mklink /J MigrationToolStorage Z:\SomeOtherFolder
