If for some reason you need to change the IP address of your AMP, here's are some simple steps to follow:
1. Plan ahead
Plan out the IP address you'll be assigning to AMP.
2. Get updated license
Since your AMP license is tied to IP address, go to https://licensing.arubanetworks.com and get an updated license key ahead of time. If you're unable to get the license key from there, then send an email to support@arubanetworks.com.
3. Commit change
Make the IP change on your AMP. The rest of the article will describe the quick way to make the change from both UI and CLI.
4. Apply new license key
Go to Home -> License -> replace license key -> Save -> re-accept licensing agreement.
5. Update other network devices
This is commonly the most forgotten piece of this process. First thing is make sure the network firewalls have been adjusted to coincide with the change. Second, if you've got your controllers sending traps to AMP, you will need to update the setting on the controller. Third, double check that firewall.
