If you have a previous installation of Directory Server, depending on its version, you can migrate to Red Hat Directory Server 7.x. Migration refers to the process of moving Directory Server 6.x files to Directory Server 7.x.
This chapter covers the migration process in these sections:
You can migrate Directory Server 6.2, 6.21, and 7.0; versions 6.11 and before cannot be migrated or upgraded to Directory Server 7.1. For these releases, as well as migrating from SunOne Directory Server, it is recommended that you export the databases to LDIF, install a fresh Directory Server, and import the LDIF data.
Before you migrate your directory service, you should become familiar with the new features offered in 7.1 release of the Directory Server.
The migration process is performed by running the migrateInstance7 script on the system where your Directory Server is installed. You must shut down your directory service before running the migration script; if you do not, the script shuts down the server.
The migration script performs the following tasks in sequence:
Checks the schema configuration files and notifies you of any changes between the standard configuration files and the ones present on your system.
Creates a database for each suffix stored in the legacy Directory Server. (In current releases of Directory Server, you can have multiple databases but just one suffix per database.)
Checks if any database exists and, if it does, gives you the option to save the database (by exporting it to a file), skip the database, or overwrite the database.
Migrates the server parameters and database parameters. (These are stored as LDAP entries in the dse.ldif file.)
Migrates user-defined schema objects.
Migrates indexes.
Migrates standard server plug-ins.
Migrates the certificate database and SSL parameters.
Migrates database links.
Migrates replication entries (changelog).
Migrates the SNMP configuration.
The migration script shuts down your legacy Directory Server before performing the migration process. The migration script also backs up your current configuration.
