Migrating Sun Java Directory Server to HP-UX Directory Server White Paper

Term Definition
slapd A conventional name for the directory server daemon. “ns-slapd” is the actual process
name that will be used by a running slapd.
SSL/TLS Protocols used for secure network communication.
Suffix Top-level entry for a directory tree. For every suffix, at least one database serves data
under that directory tree.
Migration Overview
HP developed this migration paper with special attention to the needs of Sun Java System Directory
Server consumers who are concerned about the future of their current platform. The paper provides
an easy path forward to a platform that is based on current industry standards and is supportable in
the long term. In addition, HP provides a script to facilitate tasks (such as data transformation) that
would be difficult or tedious to perform manually. This migration process has been validated for the
migration from SJDS 6.3 to HPDS 8.1.
Migration Process for a Single SJDS Instance
The migration process for a single instance of SJDS includes the following steps, described in later
sections.
1. Collecting information about the current configuration and usage of SJDS
2. Installing HPDS and creating an instance
3. Configuring or migrating certificates
4. Configuring the HPDS instance
5. Migrating the data and configuration
Migration Process for Multiple SJDS Instances
To migrate multiple instances of SJDS, most commonly deployed as the replicas in a replication
topology, HP recommends mirroring the number of systems and instances found in the SJDS legacy
topology. Each instance should be migrated individually by following the steps in this white paper,
with the exception that in case of a replicated environment, perform the data migration on a single
master only and then mirror its data to the new replicas. More details can be found in the
“Replication considerations” section.
Planning the Migration
Before beginning the migration, collect the following information about the current usage of SJDS.
This information will be used for planning, implementation and migrating the directory.

Disk Space Usage
The bulk of disk storage used by HPDS is consumed by the directory server database. This database
is stored under the /var file system. To compute how much disk space HPDS requires, measure the
amount of disk space consumed by the SJDS instance that is to be migrated. Because SJDS stores all
instance-specific components (including the database, which uses the majority of the disk space)
under the same file system path, the amount of disk space consumed under that path can be used for
