Chapter 8. Migrating from Previous Versions

This issue does not occur in cross-platform migrations or migrating using LDIF files instead of the binary databases because these already work with an LDIF copy of the database.

To migrate a replicated site, do the following:

1.Stop all old Directory Server instances and the Administration 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 8.0 packages.

•Make the first migrated master the configuration instance since it is not replicated. Then, register other master and hub servers with the first master Directory Servers configuration instance.

•This instance needs to listen on your standard port, usually 389.

5.Run the migration script, as root.

IMPORTANT

Do not set up the new Directory Server instances with setup-ds-admin.plbefore running the migration script.

#/usr/sbin/migrate-ds-admin.pl --oldsroot /opt/redhat-ds/ General.ConfigDirectoryAdminPwd=password

/opt/redhat-ds/is the directory where the old Directory Server is installed.

6.The migration process starts. The legacy Directory Server is migrated, and a new Directory Server 8.0 instance is installed using the configuration information from the legacy Directory Server.

7.Once the old Directory Server instance is migrated, test replication to make sure it is working correctly.

8.After you finish this process for all of the master server, repeat the steps for the hub servers and then for the replicas.
