Premigration cleanup
Cleaning up your IBM® Business Process Manager environment regularly is an important part of maintaining a production environment. Cleaning up IBM BPM is especially important if you plan to migrate to a new version.
The quantity and size of artifacts to be migrated affect the complexity and overall duration of the migration.
Before migrating, clean up the following items:
- Completed process instances. To remove all runtime data in the Process Server database that is associated with a completed business process definition (BPD) instance, see Removing process instances from the Process Server database.
- Completed tasks. To delete unneeded tasks from the IBM BPM task database, see Deleting tasks from the Process database.
- Snapshots that are no longer required. To delete inactive process application snapshots, see Deleting snapshots on process servers.
- Performance Data Warehouse data that is no longer required. To remove data that you no longer need from the Performance Data Warehouse database, see Running the prune command. The prune command removes data that is older than the number of days old specified by the -daysOld parameter.
- Durable subscription messages that have already been used. To delete used durable subscription messages from the LSW_DUR_MSG_RECEIVED database table, see the BPMDeleteDurableMessages command.
