I'm thinking of upgrading my instance type in my AWS EC2. Will the IP change? If so, how do I retain the ip?

P.S I'm referring to the public IP

As per Change the instance type - Amazon Elastic Compute Cloud:

Considerations for compatible instance types

Consider the following when changing the instance type of an existing instance:

• You must stop your Amazon EBS-backed instance before you can change its instance type. Ensure that you plan for downtime while your instance is stopped. Stopping the instance and changing its instance type might take a few minutes, and restarting your instance might take a variable amount of time depending on your application's startup scripts. For more information, see Stop and start your instance.
• When you stop and start an instance, we move the instance to new hardware. If your instance has a public IPv4 address, we release the address and give your instance a new public IPv4 address. If you require a public IPv4 address that does not change, use an Elastic IP address.
