You are therefore responsible for ensuring they function correctly. This guide is designed to assist you in common tasks as much as possible. Nevertheless, we recommend that you contact the [OVHcloud Professional Services team](https://www.ovhcloud.com/pl/professional-services/) or a [specialist service provider](https://partner.ovhcloud.com/pl/directory/) if you have difficulties or doubts concerning the administration, usage or implementation of services on a server. ::: ## Instructions ### Official documentation for upgrades You can either look for this document: "The Nutanix upgrades: Life Cycle Manager" or visit the official Nutanix website for archived documents: [Software Documentation: Upgrade Guide](https://portal.nutanix.com/page/documents/details?targetId=Acropolis-Upgrade-Guide-v5_20:Acropolis-Upgrade-Guide-v5_20). ### Backup As for any action on the configuration of the cluster system, it is strongly recommended to create a new backup or check the latest one. ### Items to update Some updates are done from **Prism Central**. These are updates for: - **Prism Central** itself - \*_NCC_ Some other updated must be run from the **Prism Element**. These are updates for: - **LCM** - **AOS** - **Foundation** - **AHV** :::warning Before performing an update, make sure that the versions of **Prim 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 a LCM Inventory to get a view of the software status of the Nutanix Cluster. ![First LCM Inventory](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/lcm_first_time.png) Proceed to run the first or a new Inventory update: ![Proceed LCM Inventory](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/lcm_inventory_proceed.png) After a pre-check phase, you will receive the results as soon as the inventory is done. The available upgrades will be displayed: ![LCM Result Upgrades available](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/lcm_upgrade_available.png) 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 `: ![Prism Central Settings](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/menu_prism_setting.png) 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: ![Prism Available upgrade](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/required_upgrade.png) The pre-check will be executed in any case: ![Prechecks upgrade](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/preupgrade_checks.png) If you have selected the upgrade process, the process itself will be initiated: ![Upgrade start](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/upgrade_started.png) During the execution, you might lose the connection to Prism Central: ![Prism disconnection](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/loosing_connection_prism_central.png) 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: ![End of upgrade](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/upgrade_finished.png) #### NCC upgrade If there is one or more NCC upgrades available, you can download the ones you need and then launch the upgrade: ![Select the NCC release](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/ncc_available_upgrade.png) #### 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: ![Up-to-date Nutanix cluster](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/lcm_result_after_upgrades.png) ##### **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: ![No Prism Central upgrade](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/no_upgrade.png) ##### **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: ![No NCC upgrade](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/ncc_upgrade_done.png) ### Updating Prism Element From the **Prism Central** dashboard, in the **Cluster Quick Access** frame, click your cluster. ![Upgrade Prism Element 01](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/02-update-prism-element01.png) Open the Menu and click on `LCM `. ![Upgrade Prism Element 02](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/02-update-prism-element02.png) Click the `Perform Inventory ` button. ![Upgrade Prism Element 03](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/02-update-prism-element03.png) Click `Proceed `. ![Upgrade Prism Element 04](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/02-update-prism-element04.png) Click `Back to Inventory `. ![Upgrade Prism Element 05](/images/hosted-private-cloud/nutanix-on-ovhcloud/08-upgrade-prismcentral/02-update-prism-element05.png) First, we will update **NCC**.
