Chapter 6   Migration from Earlier Versions



This chapter is intended to provide a reference of the information migrated by the migrateInstance7 script in the case of migration from a 6.x Netscape Directory Server (Directory Server) to a 7.x Directory Server. Migration and upgrade from versions 6.1 and previous are not supported in Directory Server 7.0.

For information on how to run the migrateInstance7 script, refer to the Netscape Directory Server Installation Guide.

This chapter contains the following section:


Migrated Configuration Attributes

This section explains which configuration attributes are automatically migrated by the migrateInstance7 script and which ones are not. Attributes which are not automatically migrated are either configured during the installation process for the new Directory Server or need to be configured manually for security reasons after the initial setup.
General Server Configuration Attributes

Table 6-1 lists the configuration attributes stored in the cn=config entry that are automatically migrated when you run the migrateInstance7 script.

Table 6-2 lists the configuration attributes store in the cn=config entry that are not automatically migrated when you run the migrateInstance7 script. Attributes that are not automatically migrated are either configured during the installation process for the new Directory Server or need to be configured manually. The reason for not migrating an attribute is stated in the table.

Table 6-2    Attributes in cn=config Not Automatically Migrated

Attribute Name

Reason for not Migrating Automatically

Already set up.

nsslapd-localuser

Configured during the installation process.

nsslapd-port

Configured during the installation process.

nsslapd-rootdn

Configured during the installation process.

nsslapd-rootpw

Configured during the installation process.

nsslapd-accesslog

Pathname to the log that records database access. It is set up during installation.

nsslapd-accesslog-list

Read-only attribute.

nsslapd-auditlog

Pathname to the log that records changes made to the directory database. It is set up during installation.

nsslapd-accesslog-level

Read-only attribute.

nsslapd-errorlog

Pathname to the log that records error messages generated by Directory Server. It is set up during installation.

nsslapd-errorlog-list

Read-only attribute.

nsslapd-instancedir

Configured during the installation process.

nsslapd-maxbersize

Do not change the value of this attribute unless told to do so by Netscape Technical Support.

nsslapd-plug-in

 

nsslapd-result-tweak

Reserved for future use. Do not change or remove. Doing so can have unpredictable results

nsslapd-return-exact-case

Do not modify unless you have legacy client applications that can check the case of attribute names in results returned from the server.

nsslapd-threadnumber

This attribute is not available from the Directory Server Console.

nsslapd-maxthreadsperconn

This attribute corresponds to a system parameter.


Database Attributes

All general database configuration attributes are automatically migrated. These attributes are stored in the entry cn=config,cn=ldbm database,cn=plugins,cn=config and are listed in Table 6-3.

Database-specific attributes are stored in entries of the form cn=database_instance_name,cn=ldbm database,cn=config. The attributes that are migrated are listed in Table 6-4; the ones that are not migrated are listed in Table 6-5.

Attribute Name

Reason for not Migrating Automatically

nsslapd-directory

Set up automatically during installation.

nsslapd-db-logdirectory

Set up automatically during installation.

nsslapd-db-checkpoint-interval

This attribute is provided only for system modification/diagnostics and should be changed only under guidance from Netscape Technical Support. Inconsistent settings of this attribute might cause Directory Server crashes.

nsslapd-db-durable-transactions

This attribute is provided only for system modification/diagnostics and should be changed only under guidance from Netscape Technical Support. Inconsistent settings of this attribute might cause Directory Server crashes.

nsslapd-db-home-directory

If you have several directory servers running on the same machine, the value of this attribute must be different for each instance of the directory server. Therefore, it needs to be configured manually.


Database Link Attributes

All database link configuration attributes are automatically migrated. Table 6-6 lists the configuration attributes that are common to all database links. These attributes are stored in the entry cn=config,cn=chaining database,cn=plugins,cn=config.

Table 6-7 lists the configuration attributes for a default instance of a database link. These attributes are stored in the entry cn=default instance config,cn=chaining database,cn=plugins,cn=config.
