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.
