Hi, I am running Windows Server 2019 Storage Migration Service Server to migrate a Windows Server 2012 R2 Server to Windows Server 2019. The Job, on 3 of my most important shares, says Completed with Errors"and due to the nature of the information I cannot ignore this and need to identify which folder have issues and errors. I cannot seem to find much in the Windows log files, any advise will be appreciated. Thank you.

Hi. In the Transfer Details section for each server (a pull up from the bottom of the WAC screen), there is an option to save the Error log (as CSV) then open in Excel and look at the per-file errors. The codes will all be Windows Error codes as documented here:

 

https://docs.microsoft.com/en-us/windows/desktop/Debug/system-error-codes

 

If still not able to determine why certain files aren't transfering, let me know (I reserve the right to send you to MS Support for specific troubleshooting, naturally :grinning_face:).

 

Ned Pyle | Principal Program Manager, MS | @nerdpyle on twitter

@Ned Pyle Happy to report back that I have found the directories\files that caused the issue. Another issue, after identifying the issue, correct it and the start the transfer again, it runs through every directory\file again (4TB) and it runs for 25+ hours ... Any idea? Thank you

@Kobus_Olivier It's going to examine every file, antually, but it should not be transferring them all again - you will see the difference in the transfer details page and the saved CSV. We are working on some improvements in delta transfer perf, but most customers see reduced time between transfers if there aren't many changes. How many Cores do you have on the Orchestrator and Destination computer? 

Hi, ok I understand. Both the server have dual core CPU’s with 8 GB RAM - what I am seeing now on the destination is that Windows Defender is hammering the CPU average of 60%. Is there any exclusions for Storage Migration Service? Thank you, Regard Kobus

@Kobus_Olivier Re: defender... ouch. They have always told us to expect no more than 5-10% increased utilization. As atest, if you exclude folders where SMS is writing to (or temporarily disable real-time protection), do you see the performance improve?  

@Ned PyleYes, I have disabled real time scanning and even seen and improvement. Still experiencing issues with about 22k files that have very explicit permissions (confidential data) where we cannot just go and alter these ..… Thank you for your help - appreciated.
