[..] - upgradedn userRoot: WARNING: Duplicated entry
cn=uid\=jsmith1\,ou\=Dev0\,o\=Engineering0,ou=People,dc=example,dc=com
is renamed to
cn=uid\3Djsm ith1\2Cou\3DDev0\2Co\3DEngineering0+nsuniqueid=ae8c95af-

c. Decide which duplicated entry to keep. One entry will have the standard DN. T he other has
an RDN in the format cn=cn+nsuniqueid.
d. Delete the duplicate entries. Each specific duplicate entry must be deleted manually. For
example:
/usr/lib64/m ozldap/ldapdelete -D 'cn=directory m anager' -w secret
dn:
cn=uid\3djsm ith1\2cou\3ddev0\2co\3dengineering0,ou=people,dc=example,dc
=com
e. If the entry which was kept has the renamed RDN format (cn=cn+nsuniqueid), then rename
the entry to the original DN. For example:
/usr/lib64/m ozldap/ldapmodify -D "cn=directory manager" -w secret -p

cannot be deleted.
5.3.2. Upgrading Servers in Replication
The process for upgrading servers in replication is the same as for a single server, but the order in
which the Directory Server instances is important to keep from interrupting replication. First upgrade all
supplier servers, then all hubs, and then all consumers.
Always stop directory writes to the master or hub server before beginning the upgrade process.
After upgrading all of the supplier servers, then upgrade all of the hubs and, last, all of the consumer
replicas.
Then, after the Directory Server instances is upgraded, test replication to make sure it is working
correctly.
A supplier, hub, or consumer can be migrated to a different or platform as described in Section 5.3.3,
“Migrating an 8.1 Directory Server to 8.2 on Another Machine”.
