Migrate Folder Redirection via OneDrive KFM creates duplicates
My conclusion - MS Doc regarding this process is screwed and misleading.
In the first line it say such a shift is unsuported, then it says how to do it - which btw is wrong and causes these issues as described here.
That is what works for me:
First - copy your user data in the backend using Migration Manager - the one with web console or SPMT (for those who have not tried they both do the same thing, SPMT is slightly eaiser to appraoch programmatically with PS1, but MM has nicer web console)
Second - redirect home folders to OneDrive folders on local PC
Then - KFM them via GPO or Intune (optionally, eg to get rid of GPO)
Otherwise data will duplicate
There is nice YT vids - 2 parts of how this can be done:
