RE: For firewalls, what`s best? Load-Sharing or High-Availability?

["Mikhail A. Utin" <mutin () commonwealthcare org>]

You can cut down the switching time if you install new firewall in testing environment replicating your network and 
Internet. Then you can test it and even pentest. The more time you spend working in testing the less will be in 
production.

actually depending on the architecture and policy configuration if one were to switch to another firewall, most likely 
the conversion will be very painful in a full production environment. From a Checkpoint to Cisco, the transitional 
downtime when cutting over in my experience has been no less than 4 hours, and then several weeks of pain of 
troubleshooting firewall policies that some other architect forgot to document. a transformation should be well 
documented from design to operational deployment otherwise a consulting company will take 2-3 years to even transition 
:)
