Thanks for the quick reply. My issue is this: Server A has two OUs, call them ou=A and ou=B. Server B has two OUs, ou=A (empty) and ou=C. I want to copy the data from ou=A on server A to ou=A on server B. There are no ou=B entries in the export file from server A and for the import task I add to server B, I set this attribute: nsExcludeSuffix: ou=B When this task runs, it populates ou=A on server B but also completely deletes OU=C Any way around this? Thanks for the additional info on the other question, I guess my problem is that I don't understand the significance of entry USNs at all in 389 server, so I'm not sure how to deal with them in general and especially when it comes to instance migration. _______________________________________________ 389-users mailing list -- 389-users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to 389-users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/389-users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
