My ISP has the audacity to change my dynamic IP after only two years and I had to change my IP across many different systems. I found a command and worked out the regex to replace my IP across the entire Junos configuration in a single line. Here’s how:

replace pattern "172\.16\.1\.1" with "10.0.0.1"

I was able to change address books, firewall rules, security policies, prefix lists, etc, with a single command.
