Team
Good News 

The total estimated down time took 15 min. for   migration from Cheetah
to Cougar Cluster. disclaimer: May depend on configuration (6VSVR's,10
Volume, DMIP,Mirror,Shares,Snapshots)


Cheetah at 3.2.05 migrated to Cougar at 4.0.0.061608 Dev Build.

1) On Switch, Zone the Cougar Fibre ports (SP0.2) to see the Cheetah
Storage 2) On Cheetah run system copy config 
Note:Identify secondary Flash (which need to be moved after copy) 
3) On Cheetah run system halt and Power OFF one filer at a time.

Down TIME Starts.
 
4) Place the 500MB CF in Cougar secondary slot
5) On Cougar1 run system config reset
6) Enter 'Y" to copy configuration from secondary CF
7) Cougar1 will copy and reboot
8) Repeat the steps 3 and below on Cougar2 after First Filer completely
boots 9) After cluster is formed and all VSVR's are Enabled
10) Delete the MGMNT VSVR (OLD = Lower id)

Uptime starts.

I/O Started runniing :-)

Any questions please let me know.
