Upgrading to Message Queue 4.3

Versions of Message Queue prior to Java ES 6 were delivered in two ways:

• Package-based format for UNIX-based platforms (Solaris, Linux, and HP-UX)

• File-based format for Windows

To support these past practices, Message Queue provides two upgrade paths to version 4.3:

• Upgrading to Message Queue 4.3 on the Solaris or Linux Platform

• Upgrading to Message Queue 4.3 on the Windows Platform

Upgrading to Message Queue 4.3 on the Solaris or Linux Platform

On Solaris and Linux, the installer provided with Message Queue 4.3 can automatically identify and upgrade Message Queue installations back to version 3.6, and the following instance data from the existing installation will be used by version 4.3:

• Configuration properties

• File-based persistent data store

• Log files

• Flat-file user repository

• Access control properties file

Before Upgrading – Before using the Message Queue 4.3 installer to upgrade an older version, you should review Compatibility Issues in Sun Java System Message Queue 4.3 Installation Guide in Sun Java System Message Queue 4.3 Installation Guide. You should also review Upgrading from Previous Versions in Sun Java System Message Queue 4.3 Installation Guide or Upgrading from Previous Versions in Sun Java System Message Queue 4.3 Installation Guide in Sun Java System Message Queue 4.3 Installation Guide.

Upgrading to Message Queue 4.3 on the Windows Platform

On Windows, upgrading from past versions of Message Queue to version 4.3 is not supported, but version 4.3 can coexist with past versions in different locations on the same system. As an alternative, you can:

1. Save data from the past version.

2. Uninstall the past version.

3. Install version 4.3.

4. Migrate data saved in Step 1 to the version 4.3 installation.

For information about this alternative, see Windows in Sun Java System Message Queue 4.3 Installation Guide in Sun Java System Message Queue 4.3 Installation Guide.

Refer to Compatibility Issues in Sun Java System Message Queue 4.3 Installation Guide in Sun Java System Message Queue 4.3 Installation Guide to help you decide whether to install a coexistent copy of version 4.3 or to replace the past version with version 4.3.
