Plan Your Upgrade from LANSA Composer Version 4.0
If you are upgrading LANSA Composer from an earlier version, you must upgrade first to version 4.0 and then to version 5.0. Upgrading directly from earlier versions to version 5.0 is not supported.
NOTE: As with any upgrade, you are strongly advised to make a backup of the LANSA Composer Windows server installation and the database that it uses before proceeding with the upgrade. You should also run the LANSA Composer Database Housekeeping task to cleanup, maintain and reorganize the LANSA Composer database.
Understand the Upgrade from LANSA Composer Version 4.0
LANSA Composer Server Version 5.0 installs the Windows Server using the Windows Installer (MSI) technology recommended by Microsoft for Windows software installation and maintenance.
The use of this new installation technology will make future software installation and upgrades simpler and consistent with Microsoft recommendations.
However, for this one upgrade from version 4.0 to version 5.0, some special considerations apply. Principally, the new installer will not be aware of your existing LANSA Composer Version 4.0 installation.
Future upgrades from version 5.0 to later versions of LANSA Composer will recognize your version 5.0 LANSA Composer installation details.
Overview of the Upgrade Procedure
You will treat this as a new installation, including specifying a new and different installation path for the LANSA Composer Version 5.0 software. This will leave the version 4.0 software on your system, which will be removed afterwards.
For certain aspects of the new installation, you will need to provide the details that apply to your existing LANSA Composer version 4.0 installation:
- In particular, in the Setup the Local Database step you will need to provide the details that identify your existing LANSA Composer version 4.0 database. As a result, the version 4.0 database will be upgraded and become the database for the new LANSA Composer version 5.0 installation.
- Also in the Setup the Local Database step you must identify the path to the existing LANSA Composer Server version 4.0 installation in the field. This is very important to permit the existing database to be successfully upgraded from version 4.0 to version 5.0 and to permit JAR files for transformation maps to be re-deployed to the new installation.
- Other details from your existing LANSA Composer version 4.0 installation that you may wish to re-use in the setup of LANSA Composer version 5.0 are covered in Complete your Upgrade Plan.
In addition, there are further considerations that may apply if you have other LANSA for the Web applications installed on your server. These considerations are described in item 7 of Complete your Upgrade Plan.
