You would need to add your new cluster into
your existing cluster.
You can only do this with cluster switches. (I
think you can do this with just about any 10G switch)
Personally I use NetApp CN1610 switches which
is just Cisco Nexus swtches…
There is a procedure of how you go from your
existing “switchless” cluster to a “switched cluster”, and
back again… (no down time)
When the two clusters are connected, you can
move your volume and LIFs onto your new cluster nodes… once
all data and LIFS have been migrated, you can remove the two
old nodes from the cluster and convert back to switchless
cluster.
You should be able to do all this without any
down time.
If you only want to swap the heads and not the
disks, you should also be able to do a “headswap”
procedure… again without any down time…. (netapp has a
procedure for this as well)

We have 2node FAS2520 (no switches).
How to migrate SVMs to a new cluster? Want to preserve CIFS
server names and IP addresses.
Last time we used 7MTT to do the migrations.. is there
similar tool for cluster mode migrations?
