Migrating Services Between Firewall Technologies

This paper describes the considerations that are essential to address when a corporate firewall infrastructure is replaced with new technology. The focus is on a business environment where services pass through high availability firewalls and any loss of service can immediately result in significant financial loss or worse. This paper has deliberately been written independent of specific firewall products. This is not a step-by-step guide. It is an aid to assist firewall administrators with project management issues and technical issues that could result in unplanned outages.
