Use the migration tools to migrate from an older version on one system to a newer version of WebSphere® ESB on a different, remote system. (Stand-alone servers only.)
See Overview of migrating and Premigration considerations for WebSphere ESB.
Typically, you can use the migration tools to upgrade from an older version to a newer version on the same system. However, some scenarios require that you migrate the old version's configuration on one system to the new version of WebSphere ESB on a different system. One of these scenarios is when you install new systems for your environment based on the newer version but need to migrate your existing older configuration from other systems.
For help in troubleshooting problems when migrating, see Troubleshooting version-to-version migration.
The WBIPreUpgrade command saves the existing older version configuration into a migration-specific backup directory. The WBIPostUpgrade command uses this directory to add the old configuration settings to the newer version environment.
You have migrated WebSphere ESB from the older version to a remote system hosting the newer version.
