resynchronized.
a. Reboot the Windows machine.
b. In the Directory Server Console, open the Configuration tab.
c. Expand the Replication folder, and select the database.
d. Right-click the synchronization agreement, and select Initialize Full Re-synchronization
from the drop down menu.
7. Verify the Directory Server settings.
IMPORTANT
Always verify the Directory Server configuration after migrating from 7.1 to 8.2. Some
configuration settings, like passwordMinLength for a global password policy, are not
migrated.
Review all policy settings in the new 8.2 instance and make any changes before putting the
system into production.
8. Check for any migrated entries with duplicate DNs.
Migrated instances may encounter entries which had duplicate entry DNs with slightly different DN
formats. If any entries have duplicate DNs, then it will be recorded in the error logs:
[...] - import userRoot: WARNING: Skipping duplicate entry
"cn=uid\3Dtuser1\2Cou\3DOU0\2Co\3DO0,ou=People,dc=example,dc=com" found at
line 35 of file "/opt/redhat-ds/slapd-ID/db/example.ldif"
Examine any duplicate entry messages to see if the resulting entry is acceptable. T he import utility
used during migration picks up the first entry and skips any subsequent duplicated entries. If
necessary, edit the original LDIF file, and delete the unwanted entries. Run rem ove-ds-
admin.pl to remove the newly-migrated server, and run the migration script again.
5.2.4. Migrating Replicated Servers
The process for migrating a replicated system 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 migrate all master
servers, then all hubs, and then all consumers. If any Directory Server the in replicated system will be
moved to a different machine or a different platform, use the --actualsroot and --cross parameters
with m igrate-ds-admin.pl, as described in Section 5.2.5, “Migrating a Directory Server from One
Machine to Another” and Section 5.2.6, “Migrating a Directory Server from One Platform to Another”.
NOTE
On Red Hat Enterprise Linux 5 (64-bit) machines, the m igrate-ds-adm in tool is in the
/usr/sbin directory.
To migrate a replicated site:
1. Stop all old Directory Server instances and the Admin Server.
2. Back up all the Directory Server user and configuration data.
3. Stop directory writes to the master or hub server being migrated.
4. On the machine where your legacy Directory Server is installed, install the Directory Server 8.2
