There are 2 options for a minor version upgrade.

**Option 1 - Enterprise Plans**

Bonsai clusters on Enterprise plans can send in a request to [support@bonsai.io](mailto:support@bonsai.io) for our team to perform an in-place minor version upgrade on your behalf. The impact of an in-place minor version upgrade is the same as a rolling restart: there will be a few minutes of read-only mode as it restarts.

**Option 2 - Non-Enterprise Plans**

Check out our documentation on [Upgrading Major Versions](@/docs/cluster-management/version-upgrades/upgrading-major-versions/index.md) that we also recommend for minor version upgrades. By following our variation of a blue-green strategy outlined in the documentation and assuming you can pause or buffer your updates:

- Version upgrades happen instantaneously
- Can be performed with zero downtime
- Offers recovery steps depending on your use case's approach
