No, in most cases it's not necessary to inform Algolia of a domain name change. There are a couple of exceptions to this:
- You have Single Sign-On (SSO) configured on your application(s) and the domain used for SSO is changing. If this is the case, please contact the Support team.
- You use the Algolia Crawler and the domain of the crawled pages is changing. In this case you can update the settings in your Crawler configuration to reflect the new domain. Instructions on configuring your Crawler can be found here - https://www.algolia.com/doc/tools/crawler/getting-started/crawler-configuration/.
