Do you have any scripts or policies for comparing 2 gateway clusters or 2 policies to see if they match?
Release : 10.1
1) Most obvious Policy Manager visual compare.
2) Export via policy manager or restman (the outputs are XML) You can simply diff or use notepad++ or similar tool to create a diff of the xml.
3) We have a tool that is still being developed called Graphman which is a varied version of RESTMAN. When this becomes generally available it can make a md5 of each policy and you tell if they are identical or need further review.
Graphman is available as an experimental feature in 11 and 10.1 CR03 versions of the Gateway. Please review the documentation for more information:
