Need help on Open Replicator Completion Status

Hi Team,

I am migrating some LUNS from Clariion to Vmax using Open Replicator. I had initiated migration last evening for a 1.5 TB LUN and when I checked next day Morning it was complete. I am trying to find how long it took to complete. Checked the symapi logs & also symaudit,couldn't find anything relevant which says that it was completed at this time. It only indicates when the session was created,activated.

Please help if you have any information
