"Migration expected to be pain-free" =3D> Migration requires downtime of
the entire Bobcat cluster, no not completely "pain-free" ;)
#2 There might be more than 1 box. If it is a cluster of 2 nodes or
more, they all have to go down at the same time since we would be
re-using the same configuration on the Cougar boxes.
#3 Repeat procedure for all nodes in the cluster
#4 If cluster of 2 or more, db upgrade only happens once all nodes in
the cluster are up and running
#5 there will be no reboot at the end of the FTI
#6 why need to import the volumes if luns can be rezoned to the Cougar's
WWN and the volume config is copied from the cluster DB?

Assumption #2 Change Zonda to Rocket_98. New Web first time install is
part of R98. Cougar will run R98 code. There might be more work to port
FTI to Linux, needs to be scheduled it it's not covered yet.
