Migrating to WebSphere MQ for Windows Version 7.0
=================================================
Follow this information to migrate from previous versions of WebSphere® MQ for Windows® to WebSphere MQ for Windows Version 7.0.
Before you upgrade to WebSphere MQ Version 7.0, you must consider this information.
If you migrate from a previous level of this product without first backing up your system, you cannot revert to your previous level, so back up your system before you install WebSphere MQ Version 7.0. This enables you to back out the upgrade if necessary. If you back out the upgrade, however, you cannot recover any work, such as changes to messages and objects, for example, performed by WebSphere MQ Version 7.0. For distributed platforms, information about how to back up your system begins with Backing up and restoring WebSphere MQ in the WebSphere MQ System Administration Guide.
The installation process for WebSphere MQ for Windows detects whether this is a new installation or an update from a previous level of this product. If you migrate from a previous level, all the objects that you previously created (for example, your queue managers) can be maintained. The components that were previously installed are preselected in the feature options when you install the new level. If you leave these components selected, you can keep them or reinstall them. However, if you deselect any of these components, the installation process uninstalls them.
You can also migrate to WebSphere MQ V7.0 on a system where a previous version has been uninstalled but where the queue manager data has been retained.
If an earlier version of WebSphere MQ is installed on the computer:
* Ensure that no queue managers, listeners, MQ applications or remote applications that use queue managers are running and that the WebSphere MQ Service is stopped. To stop the WebSphere MQ Service, right-click on the WebSphere MQ icon in the system tray, then click Stop WebSphere MQ.
* When the installation of WebSphere MQ Version 7.0 completes, the Prepare Websphere MQ Wizard launches automatically. Use this wizard to reenter domain, user ID and password information.
You can subsequently use the DCOMCNFG.EXE tool, shipped with Windows systems, to change the domain, user ID, and password information.This tool is described in Using DCOMCNFG.EXE to change access permissions
For Windows Vista and Windows Server 2008 users with UAC enabled only: if you do not complete the Prepare WebSphere MQ Wizard directly after WebSphere MQ installs or if for any reason your machine is rebooted between completing WebSphere MQ installation and completing the Prepare WebSphere MQ Wizard, ensure the wizard is run with Administrator privilege, otherwise the wizard might fail.
* WebSphere MQ Version 7.0 supports migration from WebSphere MQ Version 5.3 and WebSphere MQ Version 6.0 only.
* WebSphere MQ Version 7.0 does not coexist with previous versions of WebSphere MQ. You must migrate from either WebSphere MQ Version 5.3 or WebSphere MQ Version 6.0 to WebSphere MQ Version 7.0.
* By default, a typical WebSphere MQ Version 6.0 to Version 7.0 migration installs only the same features that were installed in the previous version installation. For example, if WebSphere MQ Explorer was not installed in the Version 6.0 installation, it is not installed in a Version 7.0 installation. If you want WebSphere MQ Explorer, select a custom installation of WebSphere MQ Version 7.0 and select the MQ Explorer feature on the Features panel. If you are migrating from WebSphere Version 5.3 to Version 7.0, WebSphere MQ Explorer is installed by default. If you do not want WebSphere MQ Explorer, uninstall the WebSphere MQ Explorer feature by selecting a custom installation of WebSphere MQ Version 7.0. Then deselect the MQ Explorer feature on the Features panel. For more information on how to deselect features, see Launchpad instructions in Quick Beginnings for Windows.
* Choosing not to install WebSphere MQ Explorer and WebSphere Eclipse Platform
You can choose not to install the WebSphere MQ Explorer feature, during a custom installation.
* Migrating to WebSphere MQ Version 7.0 on Windows Vista or Windows Server 2008
You can migrate to WebSphere MQ Version 7.0 on Windows Vista or Windows Server 2008 using either of the following supported migration paths:
* User Account Control (UAC) on Windows Vista and Windows Server 2008
Windows Vista and Windows Server 2008 introduce a User Account Control (UAC) feature, which restricts the actions users can perform on certain operating system facilities, even if they are members of the Administrators group.
* Launchpad migration instructions
* SPX support on Windows Vista and Windows Server 2008
* WebSphere MQ service objects
This section gives information about service objects in WebSphere MQ for Windows.
* WebSphere MQ Explorer for Version 7.0 - error connecting to a migrated queue manager
* Migrating an MSCS configuration
Migrate one node at a time, following these instructions.
