Yes. Also, the mac-address associated with the IP may change.

Depends on the type of vif.
In case of a single or lacp, you should do this before creating the
vif, however, with a multi you should not, as you risk losing up to
50% of your packets.

Again, depends if you have cluster failover on network failure on.
Best is to switch this off during these kinds of actions to avoind
unwanted takeovers (which will return the filers to their original
network config.

Whatever you do, do not forget to change the /etc/rc to reflect the
changes. If you do forget, your filer will be lost after a reboot.
