These are updates for: - **Prism Central** itself - \*_NCC_ Some other updates must be run from the **Prism Element**. These are updates for: - **LCM** - **AOS** - **Foundation** - **AHV** **Note: **Before performing an update, make sure that the versions of **Prism Element** are supported by OVHcloud and that the version of **Prism Central** to be updated is compatible with **Prism Element**.\ \ Supported versions of **Prism Element** by OVHcloud are 5.20 LTS and 6.1 STS. You can update these subversions, but it is best to wait a month after a new subversion is released.\ \ The compatibility of the version of **Prism Central** with **Prism Element** can be checked on the [NUTANIX Interoperability](https://portal.nutanix.com/page/documents/compatibility-interoperability-matrix/interoperability) website if you have a customer account on the Nutanix website.  ### Prism Central Upgrade #### LCM Inventory As documented in the official upgrade process, you should first launch an LCM Inventory to get a view of the software status of the Nutanix Cluster. To do this, select the `main menu icon` in the upper-left corner. Then, select the `Administration` submenu and then click `LCM`.   Select the `Inventory` tab, then select the `Perform Inventory` button.   After a pre-check phase, you will receive the results as soon as the inventory is done. The available upgrades will be displayed: Select the upgrades you want or update all components. You can also decide to manage those upgrades directly as explained in the next two sections. #### #### Performing the upgrade Once you are certain that you can launch the upgrade, open the `Prism Central Settings`:   If there are available upgrades, you can select the ones you need to apply, then choose to only do the pre-check or upgrade immediately:   The pre-check will be executed in any case:   If you have selected the upgrade process, the process itself will be initiated:   During the execution, you might lose the connection to Prism Central:   After a few minutes, you can connect back to the Prism Central interface, and you can then check or wait for the end of the upgrade process: #### #### NCC upgrade If there is one or more NCC upgrades available, you can download the ones you need and then launch the upgrade: #### #### Validation ##### **LCM Inventory update** Update the LCM inventory. If no upgrades are available anymore, then only the list of installed software components releases will be presented:   ##### **Prism Central upgrade validation** You can also check that the Nutanix Cluster Prism Central is up-to-date if there is no upgrade available for your cluster: Click on the `Prism Central Settings` and open `Upgrade Prism Central`. There should be no available versions:   ##### **NCC upgrade validation** You can also check that the Nutanix Cluster NCC is up-to-date if there is no upgrade available for your cluster: Click on the `Prism Central Settings` and open `Upgrade Prism Central`. There should be no available versions in the NCC tab:   ### Updating Prism Element From the **Prism Central** dashboard, in the **Cluster Quick Access** frame, click your cluster.   Open the Menu and click on `LCM`.   Click on the `Inventory` tab, then on the `Perform Inventory` button.   When the check is complete, click `Return to Inventory`.   First, we will update **NCC**. Check `NCC` and click `View Update Plan`.   Click `Apply 1 Updates`.   Click `Back to Software Updates`.   Click `NCC Check` to check the system before major updates.   Leave `All Checks` and click `Run`.   Wait for the `Health check` task to complete. You can view it in the `Tasks` menu.   Select all available updates and click `View Update Plan`.   Click `Next`.   Click `Apply # Updates`. **Note: **The update process can be very long, it is possible that some slowdowns occur but no downtime is to be expected.   ## Go further Browse all the [Nutanix guides](https://docs.us.ovhcloud.com/en/hosted-private-cloud/nutanix-on-ovhcloud/landing-page-nutanix-on-ovhcloud.md).
