 The eDirectory instance in the target server is restarted so it can use the new data.

 Network address repair is performed to start the synchronization of the new IP address in the

replica ring.

Handling Failures

During migration, the database in the source server is locked to avoid multiple copies of the instance

running on the source and target servers. Multiple copies of the same instance can lead to data

inconsistency. If the process fails and if you intend to bring up the source server again, you need to

perform the following tasks:

1 Remove the partially migrated eDirectory instance on the target server.

For more information on how to remove the eDirectory instance from a server, see Section 2.6.4,

“Using the ndsconfig Utility to Add or Remove the eDirectory Replica Server,” on page 36.

2 Restore and unlock the database in the source server.

For more information on how to unlock and restore the database, see “Using the eMBox Client

for Backup and Restore” in the NetIQ eDirectory 8.8 SP8 Administration Guide.

The database backup is saved in the

sys:ni/data

folder.

9.4 After the Migration

After migration, the target eDirectory instance listens on the IP address of the target server and not

on the source server’s address. It requires additional time after migration for the eDirectory instance

to synchronize the new IP address in the replica ring. Successful eDirectory migration can be verified

by performing eDirectory operations on the new IP address.

IMPORTANT: If you want to use the existing security certificates, you must change the IP address of

the target server to that of the source server. If you don’t want to do this, you must issue new

certificates.

NOTE: If you change the IP address of the target server after migration, you must modify the

nds.conf

file, restart the eDirectory instance, and repair the network address and partitions replica

manually. For more information on repairing eDirectory instance, refer to “DSRepair Options” in the

NetIQ eDirectory 8.8 SP8 Administration Guide.
