hi there
let me re-phrase, we have a checkpoint fw using R77 os version, and we and to migrate the whole config file to a migration tool, there is a group of securtiy rules or firewall rules in the checkpoint which are 505 rules, the migration tool (another brand) onoy can "read" and merge chunks of 400, in this case, we know that in the CLI in R80 and up you can export configuration of security_firewall rules by segments : from 1-to-300, from 301-to-505 by example.
we need to accomplish the same this under R77, we know you can only export security_firewall rules under export utility but can split the file like using CLI under R80 os version.
I hope this clarify what we need to reach.
cordially
jose
