# Upgrade

Introduced in 2024.2, the Immuta Enterprise Helm chart (IEHC) is an entirely new Helm chart used to deploy Immuta. Unlike the previous Immuta Helm chart (IHC), the IEHC shares the same version as the Immuta product. Each version of the chart supports a singular version of Immuta. Upgrading the Immuta version now entails upgrading the underlying Helm chart. Failure to do so will lead to an unsupported configuration.

| Chart name        | Common name                         | Immuta versions | Registry        | Description                               |
| ----------------- | ----------------------------------- | --------------- | --------------- | ----------------------------------------- |
| immuta            | Immuta Helm chart (IHC)             | <2024.2         | ocir.immuta.com | Version independent of the Immuta product |
| immuta-enterprise | Immuta Enterprise Helm chart (IEHC) | 2024.2          | ocir.immuta.com | Version shared with the Immuta product    |

**Upgrading from Immuta 2024.1.x or older**

If upgrading from 2024.1.x, it is first necessary to migrate to the new Helm chart, as these versions were all installed using the legacy IHC. This migration process will include upgrading Immuta.
