Importing the migration snapshot
Import the migration snapshot from the source
environment into the target environment.
Figure 1. Sample environment after the target is
started. The source environment is not running. The target can read
from the databases.
Before you begin
Make sure that the messaging engines in the target environment are started successfully before you run the BPMMigrate utility, or the command will fail with the exception: Cannot find message engine.
About this task
Run the BPMMigrate utility to import the snapshot, which includes information about configuration, LTPA keys, performance options, applications, and service integration bus (SIB) messages, from your previous version to your new version.
Important: If you decide to make configuration
changes to the source environment based on your new configuration,
you must run the utility again to take a new snapshot.
The BPMMigrate utility performs
the following tasks:
- Stops automatic generation of LTPA keys and applies the LTPA keys from the source environment to the target environment.
- Installs your applications in the target environment.
- Syncs the managed nodes.
- Runs the command to move the SIB messages from the source environment to the target environment.
- Runs the command to re-create the scheduler tasks.
- Applies the customizations from the 100Custom.xml in the source environment to the configuration objects in the target environment. For information about configuration objects, refer to Configuration objects.
- Updates the WebSphere Adapters.
Procedure
For each deployment environment that you are migrating, complete the following steps:
