How to Plan a Cloud Migration When an Application Has Hard-Coded IP Addresses

Hard-coded addresses can break after migration when services move, load balancers change, or private network ranges differ.

Checks to make

Search configuration and source for address literals, map each dependency and owner, and replace with service discovery or managed DNS where appropriate. Test name resolution and firewall policy in staging before cutover.
