How to Rename Activities
You can rename existing activities by using the new Rename 
option in the activity context menu. The Rename option is enabled when the selected activity and all jobs in the activity are deactivated.
Renaming a activity might last longer for activities with larger number of discovery jobs.
Also, renaming the activities would result in renaming of all of the jobs in the corresponding discovery activities. It means that new directories for these jobs will be created in the C:\hp\UCMDB\DataFlowProbe\runtime\communicationLog directory of the probes. This can result in much increased disk usage as the size of the logs (if always enabled) could run into gigabytes. So manual cleanup of the communication log directories belonging to the jobs with the old management zone naming would be required .
Rename Activities
To rename an activity,
-
Go to Data Flow Management > Universal Discovery > Zone-based Discovery.
-
Right-click the activity you want to rename, and then select Rename
from the context menu.
Note If the Rename
option is disabled, click Deactivate 
to deactivate the selected activity and all of the jobs in the discovery activity. - Enter the new activity name, and then click OK.
- Go to the C:\hp\UCMDB\DataFlowProbe\runtime\communicationLog directory, perform a backup of the communication log directories belonging to the jobs with the old activity naming (if necessary), and manually clean up these directories.
