NS480 VNX data replication

We have a new VNX and are trying to migrate the data from our current NS480 over to it.

I started with this guide

http://www.emc.com/collateral/hardware/white-papers/h8174-migrating-celerra-vnx-replicator-wp.pdf

The steps failed at data mover interconnect. Reading other discussions, several people recommended the command line versus the replication wizard.

Although I have got a little more with the CLI it's still failing at the data mover interconnect.

The following just sits at 1% progress

$ nas_replicate -create NS480VNX -source -vdm vdm1 -destination -vdm vdm1 -interconnect NS480-VNX -max_time_out_of_sync 10

$ nas_task -i 6761780

Task Id                = 6761780

Celerra Network Server = NS480-NN-Control

Task State             = Running

Current Activity       = Info 26045317578: Creating checkpoints for Create task

Movers                 = server_2

Percent Complete       = 1

Description            = Create Replication NS480VNX.

Start Time             = Sun Nov 24 22:17:12 EST 2013

Estimated End Time     = Tue Jan 07 09:38:52 EST 2014

Schedule               = n/a

I maybe missing something simple which needed to be done with the new VNX... Any input would be appreciated!

Thanks
