KFM in combination with SharePoint Migration Tool creates duplicates

[gvkempen]

Hello all,

I am working on the rollout of OneDrive for our users using Known Folder move. At the moment we have these folders redirected to a file share and is the data offline available. As most users have a lot of data I am using SPMT to perform an initial load as described at https://docs.microsoft.com/en-us/onedrive/redirect-known-folders#transition-from-the-windows-folder-.... When I then disable the redirection and enable the move using GPO everything seems to work fine, except that it’s not merging the folders, but creating duplicate files. I have tested with disabling offline folder sync, but that did not make a difference. When I try to move manually the OneDrive client says it found files with the same name and will add “-Copy” to the new files to preserve both files. I understand that, but according to the documentation it should not create copies but merge the folders during the move.

I there anyone who has gone through this process that can help me out?

Regards,

Gert

Wow this is big, I'd love an answer on this as we were just thinking about using SPMT to seed users folders to OneDrive.

Hi @gvkempen, so how did you actually manage to reconcile the duplicated files?
I'm curious to know to use either KFM https://docs.microsoft.com/en-us/onedrive/redirect-known-folders#transition-from-the-windows-folder-... or SPMT https://docs.microsoft.com/en-us/sharepointmigration/fileshare-to-odsp-migration-guide.

Hello @SystemEngineer. Even after opening a call with Microsoft I was not able to get it fixed. It's a bug they told me that will be fixed some time (hopefully). KFM works fine as long as you migrate to a clean OneDrive. As soon as you prefill OneDrive using SPMT and then use KFM to redirect and copy the last changes from the users pc it creates copies. I finally used SPMT in combination with folder redirection to e.g. %OneDrive%\Documents as a workaround. That works, but requires me to run a delta migration once the GPO is applied. So a bit more work and planning.
