Amazon Lightsail IP change

[stsvoip318]

If I failed to set a static on my Amazon Lightsail instance, and that previous IP was registered to my FQDN, is it easy to change the FQDN IP to the new one?

If you currently have a dynamic IP, and you wish to change to a static IP, then read over this tread.
Very similar to changing from one static IP to another. Change, restart services, wait for DNS propagation.
