You can use the restoreConfig and wsadmin commands
to roll back a migrated WebSphere® Application Server Version 9.0 stand-alone application
server to the state that it was in before migration.
Before you begin
Supported configurations: This article is about profile configuration migration. To

Best practice: When migrating a
Version 7.0 or later stand-alone application server, the best practice is to perform
the following actions if you want to be able to roll it back to its
previous state after migration:
- Run the backupConfig command or your own preferred
utility to back up the Version 7.0 or later stand-alone application
server configuration.
Important: Make sure that you note
the exact name and location of this backed-up configuration.
See backupConfig
command for more information.
- Migrate the stand-alone application server.
- If necessary, you can now roll back the stand-alone application
server that you just migrated.
Procedure
- Stop all of the servers that are currently running in the Version 9.0 environment.
- Perform one of the following actions to restore the Version 7.0 or later configuration for the stand-alone application server.
- If you chose to keep the installed applications in the
same location as the prior release during migration to Version 9.0 and any of the Version 9.0 applications are
not compatible with the prior release, install applications that are
compatible.
- Start the rolled-back stand-alone application server in
the Version 9.0 environment.
Results
The configuration should now be returned to the state that
it was in before migration.
What to do next
You can now restart the migration process if you want to
do so.
