Description:
As SAP Adapter 7.0 release note described, if we need migrate SAP Adapter from 5.4.1 to 7.0, we first need migrate to SAP Adapter 6.2.1. Refer to the following migration steps for migrating a project from 5.4.1 to 6.2.1.

Detailed steps for migration from SAP Adapter 5.4.1 to 7.0.

To migrate an existing project from 5.4.1 to 6.2.1, follow the steps below.

1). Open the existing project in TIBCO Designer where there is a running SAP Adapter 6.2.1.

2). Select one of the adapter configurations from the project. The message "Loading R/3 Product Classes" indicates that the required configuration is being added to the existing project.

3). For all  adapter configurations in the project, refresh the SAP schema for any Request-Response Invocation Services. You do not need to refresh the SAP schema for the Publication Services, Subscription Services, and Request-Response Services.

4). Save the project.

5). These steps are outlined in the SAP Adapter 7.0 documentation. Refer to the section entitled, “Migrating a Project by Using TIBCO Designer”.
