Migrating product configurations with migration tools

Migration support consists of tools that are included with WebSphere® Application Server. These tools primarily provide support for saving the configuration and applications from a previous version of the product into a migration-specific backup directory and then importing that configuration into the latest version of the application server.

Before you begin

Supported configurations Supported configurations:

This article is about configuration migration, such as migrating deployment managers and federated nodes in a network deployment environment. The Application Migration Toolkit for WebSphere Application Server provides support for migrating applications from previous versions of WebSphere Application Server to the latest product version. For information about migrating applications, read more about the Application Migration Toolkit.

Read Overview of migration, coexistence, and interoperability and Premigration considerations. For resources to help you plan and perform your migration, visit Knowledge Collection: Migration planning for WebSphere Application Server.

Important: Use the migration tools for the version of WebSphere Application Server that you are installing. The tools change over time. If you use migration tools from an earlier release of WebSphere Application Server, you are likely to encounter a problem with the migration.

The migration scripts are located in the app_server_root/bin directory after installation.

Procedure

Select the appropriate migration tools to migrate your product configurations.

convertScriptCompatibility tool
Administrators use the convertScriptCompatibility tool to convert their configuration from a mode that supports backward compatibility of Version 6.1 or above administration scripts to a mode that is fully Version 8.5.

Read convertScriptCompatibility command for more information.

convertSelfSignedCertificatesToChained task
Chained certificates are the default certificate type in WebSphere Application Server Version 8.5. Administrators can use the convertSelfSignedCertificatesToChained task with the wsadmin tool to convert self-signed certificates to chained certificates.
