Thanks I would like to avoid the pitfalls of the migration myself that is why I work with a PA engineer and also like to get different view points on the community boards. I began learning PA last December when we implemented our first and then configured our second along with managing all other areas of the network. The intent of my migration from an ISA 2006 firewall is to move foff of old technology to better improve over all security. Currently different users are give access or blocked from access to certain web sites via the proxy server based on GPO. The first step we took was to create security policies based on the level of access allowed to a certain type of user. Next step is to enable those policies on the PA and slowly remove those blocked site from the ISA and assure that the PA is doing all the filtering. Next will be to change the rules and the GPO's so that the users,at all facilitues,no longer go through the ISA but directly to the PA.
