 EMC® SAN Copy™ and Open Replicator Migration from EMC Storage to EMC XtremIO™ Technical Notes Rev 02 May 7, 2015
Hi, I am planning to use Open Replicator for moving few clustered servers from Vmax to Xtremio. I have not done hot push before, I have zoned 4 ports from vmax to xtrem. Now my concern is while creating the OR session should i select pre-copy, differential and consistent or can should i select only one of the options. Onemore question is should I set  ORS port ceiling % to the 4 ports I am using for migration. If anyone provide me the right way to use hot push that would be helpful .
