Sure thing Sumanth.  What document specifically are you seeing the note about hot pull requiring a license? You do not need a license for hot pull on VMAX3, but you do need a license for hot push on VMAX1.  And yes, with a hot pull you essentially do the following:  - Set up zoning/masking - Create Open Replicator sessions - Shutdown production - Activate Open Replicator sessions, beginning the background copy operation - Switchover production to the new array  You do not need to wait for the copy to complete before starting the application on the VMAX3 -- the VMAX3 will continue the background copy operation... and if the application requests data that hasn't been copied yet, Open Replicator will reach back to the VMAX1 to service the request (transparently to the application).  Thanks,  - Sean
Hi Folks,  I have a few questions surrounding the process of using the OR to migrate data between VMAX1 and VMAX3. The production is currently running on VMAX1 and the data need to be migrated to VMAX3  1. Can I use Hot Push? 2. What licenses do I need for HotPush OR? Should I check them on both arrays or just on the Production array? 3. Can VMAX 1 in this instance be the "Control Array"? 4. Zoning !!!!      a. Get the list of ALL FA's of all the control devices and the remote devices and zone them on the SAN      b. Discover the arrays using the "symsan" command       5. Masking -- Mask all the remote devices on VMAX3 to controlling FA's using the symaccess command on VMAX3 6. Make sure the remote devices are not accessed by any hosts during the migration 7. Create the OR sessions using a file and symrcopy command and activate it.  Please let me know of any mistakes or anything that I might have overlooked.  Thank you, Sumanth
