You can update a pack in the Source Control Management (SCM) server, and then import the updated pack to OnCommand Workflow Automation (WFA).
If you make any changes or updates to a pack in the SCM server, the admin or architect needs to resolve the conflicts, if any, using the SCM-provided diff tools. WFA tailors the XML diff file to show only the relevant changes.
Before importing the pack, you are notified about the changes going in to the WFA pack content.
