When you migrate groups with the Active Directory Migration tool, you may receive the following error message in the Active Directory Migration log file:
A net helpmsg for 8539 yields the following error text:
SID History cannot be updated for group because the SID for group already exists in the forest. rc=8539.
The source object's SID already exists in destination forest.
This error can be caused by renaming the group and then migrating it again. The security identifier (SID) in the SID history can only exist in one place in the forest.
