We have 4 node cluster(ontap 9.1) and we are planning to move our nfs vol to new node aggr which is newly added.
The first question is, can we move nfs vol nondisruptively to other node?
The second question, after move vol to new added node, which lif is going to serve to nfs vol? Because there is no lif option when you moving volume ?
See The Solution
The volume move command is disruptive, mostly.
There's the time it takes to do the last snapmirror transfer while we quiesce the IO on the front end before updating the VLDB to point to the new volume location.
The default cutover delay is 30 seconds.
See the man page for the command: http://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.dot-cm-cmpr-920%2Fvolume__move__start.html
As for your second question ... NFS 3 will continue to use the same LIF.
Best practice would be to migrate the LIF to the new node when you move the volume.

I think you mean non-disruptive 🙂
