Changing of IP address to the existing farm will not break anything with SharePoint. But be sure to consider the following tips while changing the IP.
- Change your DNS records to point to the new IP address for all web applications.
- Change the IP addresses for the SQL Server and SharePoint.
- Check IIS on your SharePoint server to see if the new IP address is correctly configured for all web applications in the server.
