Upgrading the connector involves installing the latest adapter files and loading the latest ABAP transport files for the ABAP Extension Module. For additional upgrade information, see the Implementation Guide for WebSphere MQ Integrator Broker, or, for IBM WebSphere InterChange Server, see the System Installation Guide for UNIX or for Windows.
It is recommended that you backup your current connector files (for example the configuration and message files CN_SAP.txt and SAPConnector.txt) before starting. Before loading the connector definition into the repository, you may want to remove all supported object references except those you need.
Attention: If you install the latest Primary and Number Range transport files, you will overwrite your existing number range interval information. Overwriting the number range intervals may cause existing events and objects to be out of sync because the number range interval is reset to zero (0).
After you install the latest version of the connector, install the latest ABAP transport files for the version of SAP you are going to use. Without these, you cannot transport the existing components of the ABAP Extension Module. Transport installation is described in Connector transport file installation. Keep in mind that installing new transport files overwrites any modifications to adapter-delivered code.
Make sure that you use the correct transport files for your environment. For example, if you are using an SAP R/3 version 4.6 environment, install the adapter's 4.x transport files. Doing so ensures that any warning or errors you get when you load your objects are in relation to the SAP R/3 version 4.x environment and not anything else that was brought over from SAP R/3 version 3.x. This allows you to resolve problems that relate to differences in SAP R/3 version 4.x.
After you install the latest version of the connector and the latest ABAP transport files for the version of SAP you are going to use., configure the new connector.
If your are upgrading from the C++ version of the connector to the latest Java-based version, you need to configure the new connector-specific configuration properties Modules and Namespace. For more information on these properties, see Connector-specific configuration properties.
