Sun Microsystems Sun Java System Directory Server Enterprise Edition 6.0, Migration Giude

Page: 27 / 148

Deciding on the New Product Distribution
Directory Server 6.0 is provided in two distributions:
■
Java Enterprise System distribution. This distribution takes the form of operating
system-specific packages, such as
pkg
for Solaris and
rpm
for Linux.
■
Compressed archive (zip) distribution.
There are two major differences between these two distributions:
1. Installation from zip can be done anywhere on the system and as a non-root user. The Java
Enterprise System distribution requires installation as a super user. It is also more difficult
from an automated deployment perspective to install the packages anywhere but in the
default location.
2. The zip distribution can be installed as many times as required and multiple distinct
versions of the same product can coexist on a single operating system instance. This is not
true for the Java Enterprise System distribution. The new version of certain shared
component packages required by Directory Server are incompatible with the previous
version of these packages. When you migrate to the new version of Directory Server using
the Java Enterprise System distribution, the old Directory Server version will no longer run
on that machine.
Depending on your environment and the specific requirements of your organization, select the
appropriate packaging format. Note that the Sun Java Web Console is currently available only
in the Java Enterprise System distribution.
Outline of Migration Steps
Migration to Directory Server 6.0 can be broken down into the following distinct steps:
1. Migrating the Schema
2. Migrating the Security Settings
3. Migrating the Configuration
4. Migrating the Data
5. Migrating the Plug-Ins
6. Post-migration tasks
To avoid unforeseen problems with the migration, these steps should be performed in the order
listed above. In certain cases, you can automate some or all of these steps, using the
dsmig
command. The following section indicates what can be automated and what must be done
manually, depending on your existing deployment.
