Rolling back your environment
After migrating to IBM BPM V8.0.1, you can roll back to the version you migrated from. This returns the configuration to the state that it was in before migration. After rolling back the environment, you can restart the migration process.
Generally, migration does not modify anything in the configuration of the prior release; however, there are cases where minimal changes are made that are reversible—those of a dmgr and its managed nodes.
The following subtopics provide further information for these cases.
- Rolling back a deployment cell
You can use the restoreConfig and wsadmin commands to roll back a migrated IBM BPM V8.0.1 deployment cell to an earlier version. This returns the configuration to the state that it was in before migration. After rolling back the deployment cell, you can restart the migration process.
- Rolling back a managed node
You can use the restoreConfig and wsadmin commands to roll back a migrated IBM BPM V8.0.1 managed node to the state that it was in before migration. For each managed node that you want to roll back, you must roll back the managed node itself and the corresponding changes made to the master repository located on the dmgr.
