[cisco-voip] 7->9 jump upgrade cutover

[Ed Leatherman]

Hello!

Anyone have experience with flash cutting a cluster? Jump upgrade guide
just says disconnect old cluster and connect upgraded cluster - is there a
more graceful way to do this with phone registrations? Should I shut down
CM service on the old cluster first or will the phones/new cluster sort out
all its tcp sessions cleanly if I just swap network connectivity?

I've got matching firmware on both clusters and the database appears to be
in good working order on the new cluster, just want to minimize any
surprises.

Thanks!

Ed
