Just changing the host name should be enough, it will be updated via Autodiscover. Therefore you need to ensure that you have autodiscover.example.com on the SSL certificate as well.

Set the internal and external host name as required and then restart IIS.

If you were using another host name which wasn't dynamic DNS I would suggest to put the old host name in to the SSL certificate. However that isn't possible with a dynamic DNS host. Therefore it will have to be Autodiscover at point of connection.

The IP address isn't really going to make much difference, because the host name is key here.
The client may well connect and throw an error. It could be argued that using a different IP address is probably best. That will stop Outlook from connecting on the old URL and getting an SSL error and then it should trigger Autodiscover to do its thing and direct the users to the new server address.
