About Release 5U1

Release 5U1 Directory Server is a maintenance release that fixes bugs in Release 5 Directory Server. For more information, see the Sun Java System Directory Server Enterprise Edition 6.2 Release Notes.

Java ES Release 5U1 Upgrade Roadmap

The following table shows the supported Directory Server upgrade paths to Release 5U1:

Table 3–1 Upgrade Paths to Java ES 5 Update 1: Directory Server 6.2

Java ES Release	Directory Server Release	General Approach	Reconfiguration Required as Part of Upgrade
Release 5	Sun Java System Directory Server 6.0	Maintenance upgrade. Apply patches.	None
Release 4		Direct upgrade of Directory Server from Release 4 to Release 5U1 is not supported. This upgrade path is supported by first upgrading Release 4 Directory Server to Release 5 Directory Server and then upgrading Release 5 to Release 5U1. The information about upgrading Release 4 to Release 5 is documented in Sun Java ES 5 Upgrade Guide for Microsoft Windows.

Directory Server Data

Directory Server 6.x configuration is performed using the Directory Service Control Center or the Directory Server Enterprise Edition command-line utilities.

The following table shows the type of data that can be impacted by an upgrade of Directory Server software to Release 5U1.

Table 3–2 Directory Server Data Usage

Type of Data	Location	Usage
Directory Server configuration data	Directory Server 6.x: accessed through Directory Service Control Center and Directory Server EE command-line utilities	Configuration of Directory Server
Directory Server schema		Define structure and semantics of data in the directory
Security data	Directory Server 6.x: SSL configured through Directory Service Control Center and Directory Server Enterprise Edition command-line utilities	Server certificates
User data	Directory Server	Server certificates

Directory Server Compatibility Issues

Release 5U1 Directory Server does not introduce any interface changes and is therefore backwardly compatible with Release 5 Directory Server.

Directory Server Dependencies

Dependencies on other Java ES components can, in general, impact the procedure for upgrading Directory Server software. Directory Server has dependencies on the following Java ES components:

• Shared Components. Directory Server has dependencies on specific Java ES shared components (see Table 1–8. Directory Server upgrades might depend upon upgraded versions of these shared components.

• Directory Proxy Server. Directory Server has a co-dependency on Directory Proxy Server for providing improved security and performance for LDAP requests.
