I have 2 IP380s (VRRP) running NGR55 & will be upgrading this weekend to
NGX 61.. I have read in the upgrade guide (NGX6R1) that it's possible to do an upgrade with Zero downtime..I am curious has anyone tried to do this..& succeeded?..Also any tips or suggestions would be greatly appreciated.
Thanks in advance,
Larry Milliken
