You can change the availability domain of an existing Autonomous AI Database instance using the Oracle Cloud Infrastructure Console. Changing the availability domain allows you to place Autonomous AI Database instances and related Oracle Cloud Infrastructure resources, such as compute VMs, in the same availability domain to minimize network latency. Similarly, you can also select an availability domain when creating or cloning an Autonomous AI Database instance via available APIs.

See [Specify an Availability Domain when you provision a new instance using the API](https://docs.oracle.com/en/cloud/paas/autonomous-database/serverless/adbsb/autonomous-provision.html#GUID-17A0E50E-33F2-45BD-A704-21347B287192) and [Change Availability Domain on the OCI Console](https://docs.oracle.com/en/cloud/paas/autonomous-database/serverless/adbsb/view-network-information.html#GUID-F19D104D-76C5-4091-B485-58653C5F0369) for more information.
