Repeat the same command to perform incremental copies. As dynamox suggested, you can create a batch file and output log filename with date appended to the filename and run it in scheduler.  Its worth looking at the logs to see which directories were missed. Also, only (and only) for the purpose of the migration, you can add the user that is running the emcopy command to the Isilon (target) share permissions with "run-as-root" permissions. Once migration is completed, that privilege must be removed.  I have used an inexpensive (commercial) tool (beyond compare) in the past to compare files and directories. I have to mention though that EMC does not recommend or suggest using any particular tool for comparing data.
