Hello Sagi,  Donor update is only possible when you are pulling data onto a Symmetrix or in OR terms when you are doing a HOT PULL. If you wish to move data from Symm to Netapp, i believe you would have to go with a push operation which moves data off to the netapp, in which case you do not have the donor_update option available. Refer the migration CLI attached. Hope it helps.  Regards,Roshan Raju.
Hey All !  I need to migrate VM machines from Symmetrix to Netapp machine and i'm choosing the Open Replicator for the migration tool. I familiar with the option that called "Donor Update" that saves me lots of downtime (by turning on VMs to production while copy session running in background). But,  I used to do this option on Symmterix to Symmetrix migration.. now i need to do an Symmetrix to Netapp migration! Can I bring VMs to online while doing OR copy session from Symmetrix to Netapp? or that feature only available if both arrays are EMC's ?  Thank you all!
Donor Update option on OR session - DMX to Netapp
