FMA 7.4 physical/HA -to- CTA9.0/VE migration

Hi all,

Any thoughts on the best way to go to migrate from a FMA/HA configuration based on physical hardware to a CTA/VE enviroment running under vSphere?

Environment: currently Celerra/NS (both source and target), migrating to VNX (also both source and target)

- steps to take

- are there costs in upgrading from FMA7.3 to CTA9.0 if customer has an active servicecontract on FMA

- thoughts on performance virtual versus physical

- thoughts on costs and availabilitu virtual versus physical

- caveats

- tips

- tricks

Thanks in advance!
