A post to record some researches:
Go to kb.netapp.com and ask a question or checkout the How To’s:
In the clustershell
set -priv diag
volume add-other-volumes -node nodename
*Add 7-mode volumes to the cluster database
Note: The "add-other-volumes" switch can only be used with VTW (volume transfer wizard) which uses snapmirror to migrate data volumes from 7-Mode systems.

Is this the correct procedure for headswap on a V-Series?
1) Gather existing v-series head configuration
2) Zone and LUN mask the new v-series head to the existing LUNs
3) Perform a disk reassign ownership on an aggr by aggr basis
4) Create new CIFS shares on new v-series head (only CIFS shares on existing v-series head)
5) Remove old v-series head from DNS (or swap servers in DFS)
6) Add new v-series head to DNS
7) Verify client connectivity
1) The old heads are x86 (V3020) and new heads are x64 (N6040 / V3120), therefore the binaries are different.
2) NetApp ONTAP on old heads, IBM ONTAP on new ones
How about if I do a config dump and a config dump -v on the old heads and do a config restore on the new ones before swinging the aggrs?
They are both running 126.96.36.199 (had to downlevel the N6040 for snapmirror purposes).
For 1) you are creating a new aggr and migrating data. The aggregates on a V-Series are raid0 (aggr options aggrname to see it), so you can't fail a drive/lun per se.
For 2) you are correct on most of the steps, but as you will be retaining your root volumes, there's no need to re-create shares or change dns etc.
1. Halt existing HA Pair and power off the nodes
2. Rack and cable the new cluster, power on the nodes and go into maintenance mode.
3. Verify that the ports you want to use are initiators and document the WWPN's (storage show adapter)
4. Update the zoning on the switches for the new initiator ports
5. On the back-end SAN, update your host profile to reflect the new WWPN's
6. From maint mode, reassign the LUNs from the old systemID to the new one, repeat for the other node.
7. Using aggr status from maint mode, validate that you can see your various aggrs and that you have one marked as a root aggr on each controller.
8. Halt both nodes and boot them up normally.
9. Upgrade ONTAP if you are changing CPU architectures.
As a pre-step, you might want to validate that the version of ONTAP that's on the CF of the new controllers is compatible with the version of ONTAP (raid labels etc.) on the old. You may want to upgrade ONTAP before doing the head swap.
