# Can I Resize an Instance Across Availability Zones?

## Problem

I need to resize an instance to a flavor which has metadata associated with a separate Availability Zone (AZ). Is it possible?

## Environment

* Platform9 Managed OpenStack - All Versions
* Nova

## Answer

No, instances cannot be resized to a flavor which would schedule the instance to a separate AZ than the one in which it was spawned initially. Although you may be able to live-migrate an instance to a host residing in a separate AZ due to an [upstream bug](https://bugs.launchpad.net/nova/+bug/1452568) (if using an outdated CLI) or by using the **`--force`** flag, this will not actually change the AZ of the instance, and is highly discouraged.
