I'm trying to migrate users from an OU with its own partition to another partition in Imanager. When moving users from one partition to the other, we get a -611 error. I've never seen this before and can't seem to find much info on it online.

(Error -611) An attempt to create an object violated containment rules.

I thought maybe it had something to do with the partitions so I attempted to just merge the partition to the root partition , but got a -637 error.

(Error -637) After an object has been moved from one context in the tree to another, the Directory database will not allow that object to be moved again until all replicas of that object have been updated.

As far as I know, nobody has has made any changes in the tree for a long time. We've been doing this process ever summer for years and have never had any issues.

I ran ndsrepair -U on all of our replica servers and they are all reporting 0 errors. Any ideas?
