## Issue

When moving a flow from one instance of Hyperscience to another (e.g., from a development instance to production), a “Release with given UUID does not exist” error could appear in the Flow Studio for the imported flow.

## Affected versions

V31 and later

## Affected configurations

All configurations

## Cause

The imported flow is looking for a release with the UUID from the original instance.

## Solution / Workaround

1. Export the release from the original environment.  
   - For more information, see “Exporting a Release” for your version of Hyperscience ( [v38](https://help.hyperscience.ai/general-information/docs/v38-exporting-a-release) | [v39](https://help.hyperscience.ai/v39/docs/exporting-a-release) | [v40](https://help.hyperscience.ai/v40/docs/exporting-a-release) | [v41](https://help.hyperscience.ai/v41/docs/exporting-a-release) | [v42](https://help.hyperscience.ai/v42/docs/exporting-a-release) | [v43](https://help.hyperscience.ai/v43/docs/exporting-a-release)).
2. Import the release into the destination environment.

3. (v32 and later) Assign the release to the flow in the destination environment.
