Migration support consists of tools that are shipped as part of
WebSphere Application Server Version 6.1 that primarily provide support for
saving the configuration and applications from an older version of WebSphere
into a migration-specific backup directory and then importing that configuration
into Version 6.1.
Before you begin
See Overview of migration, coexistence, and interoperability and Premigration considerations.
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.
All of the migration scripts
are in the app_server_root/bin directory
after installation.
Procedure
Select the appropriate migration tools to migrate your product
configurations.
- WASPreUpgrade tool
- Saves the applications and configuration data from a previous installation
of WebSphere Application Server to a backup directory.
See WASPreUpgrade command.
- WASPostUpgrade tool
- Restores the configuration data from a previous release.
The WASPostUpgrade tool
reads the data from the backup directory where the WASPreUpgrade tool
stored the data.
See WASPostUpgrade command.
- clientUpgrade tool
- Upgrades the client application to a new release level.
See clientUpgrade script.
- convertScriptCompatibility tool
- Used by administrators to convert their configuration from a mode that
supports backward compatibility of Version 5.x or 6.0.x administration scripts
to a mode that is fully Version 6.1.
See convertScriptCompatibility command.
What to do next
