Our network team is moving from Juniper to Cisco , they are going to change network switches to which our on-prem NetAPP array is connected which in turn will result in different IP addresses for data LIFs, intercluster LIFs , node and cluster management and Service processor.
a) Has anyone performed this type of change ?
b) How much downtime would this cause , seems like NFS would not be accessible by hosts and snapmirror relationship would break ?
c) I guess i need to open firewall ports for NFS and snapmirror again with new IP address.
c) Do we need to run snapmirror initial copy again, i hope it would take long time ?
d) What if i ask them to move entier VLAN and provide same IP on new switches, would it be non-disruptive ?
