Example Pre-Deployment Checklist
Allowlists—Update your allowlists for any new domains.
Custom Visualforce pages or custom apps—Replace references to the org’s instance URL with relative URLs and dynamically generated hostnames. Note any URLs that require a hard-coded reference.

External software that accesses your Salesforce org—Verify that the external software that uses your Salesforce URLs, including site URLs, can process redirections. If the software can’t process those redirects, work with the software owner to get that redirection functionality in place or plan to update your use of the software with your new URLs after you deploy the change.
Firewalls and Proxy Servers—Update trust settings that filter by hostname. Include all applicable URL formats for your new configuration.
Identity providers on your Salesforce login page—Note any authentication options available to your users.
Installed Packages from AppExchange—To get the latest fixes, potentially including fixes for enhanced domains, install the latest version of each package. Note the package providers so that you can report any issues detected.
