# Alter a Deployment

Learn how to modify an existing deployment.

Modifying certain aspects of a deployment, such as the region, requires assistance from the FusionAuth team.

To upgrade the version of FusionAuth used by a deployment, see [Upgrade a Deployment](https://fusionauth.io/docs/cloud/upgrade-a-deployment.md).

Please open a [support ticket](https://account.fusionauth.io/account/support/) to change any of the following attributes of your deployment:

*   the type (basic, business, or high availability)
*   the region or geographic location
*   the size of each compute node
*   the number of compute nodes
*   your database size and class
*   the hostname
*   any database redundancy attributes

These changes are typically handled in 1-2 business days, and in certain contexts may require changes to your billing/contract.
