The upgraded commitment term\nbecomes valid at 12 AM US and Canadian Pacific Time (UTC-8, or UTC-7 during\ndaylight saving time) on the day following the upgrade operation, and you begin\nto receive the new CUD percentage that is applicable for your upgraded\nterm.\n\nUpgrading your commitment's term changes the\n[term extension eligibility window](/compute/docs/committed-use-discounts/extend-commitment-term#term-extension-eligibility-window)\nfor your commitment. After the term upgrade takes effect, Compute Engine\nupdates the eligibility window to remain open up to 1 year from the start date\nof the ongoing term. Upgrading the term doesn't affect the following properties\nof your commitment:\n\n- Name\n- Start date\n- Region\n- Project\n- Commitment type\n- Auto renew status\n- Committed resources\n\nThe process of term upgrade remains the same regardless of whether your\ncommitment has a preset term length or a custom term length. Any attached\nreservations for your commitment continue to exist throughout the\nlifetime of your upgraded term, unless you manually replace them.\n\nExample of an upgraded commitment\n\nThe following table shows an example where the term of an existing commitment\n(`commitment-1`) gets upgraded by 2 years:\n\n| **Commitment property** | **Before term upgrade** | **After term upgrade** |\n|----------------------------------------------|----------------------------------------|----------------------------------------|\n| Name | commitment-1 | commitment-1 |\n| Type | N2 | N2 |\n| Region | us-central-1 | us-central-1 |\n| Project | example-project-1 | example-project-1 |\n| Resources | - vCPUs: 200 \u003c!-- --\u003e - Memory: 200 GB | - vCPUs: 200 \u003c!-- --\u003e - Memory: 200 GB |\n| Term | 1 year | 3 years |\n| Start date\\* | January 1, 2020 | January 1, 2020 |\n| End date† | January 1, 2021 | January 1, 2023 |\n| Term extension eligibility window open until | May 1, 2020 | January 1, 2021 |\n| Auto-renew status | Disabled | Disabled |\n\n\n^\\*^Commitment starts at 12 AM US and Canadian Pacific Time\n(UTC-8 or UTC-7) on the specified start date. \n\n^†^Commitment ends at 12 AM US and Canadian Pacific Time\n(UTC-8 or UTC-7) on the specified end date.\n\n\u003cbr /\u003e\n\nQuota considerations\n\nYou don't typically need to request additional quota when you upgrade your\ncommitment's term. However, if you upgrade a commitment's term on the same day\nthat it expires, you must [verify](/compute/docs/instances/signing-up-committed-use-discounts#to-check-quota-in-the-console)\nthat you still have sufficient quota available. That's because on the day that a\ncommitment expires, whatever quota the commitment was using up gets released\nback into your pool of available quota, and it might get used up by your other\nbusiness needs.\n\nPricing implications\n\nYour commitment fee is the sum of the discounted prices of all your committed\nresources. When you upgrade your commitment's term, Compute Engine\napplies the new 3-year CUD percentage and recalculates the discounted price for\neach committed resource. To do this recalculation, Compute Engine uses\nthe prevailing on-demand price of each resource on the day your original term\nbecame active. This new discounted price for each resource stays the same until\nthe end of your upgraded term, even if the on-demand prices change.\n| **Note:** If you merge or split your commitments, then the discounted prices for your committed resources might change on the day your merged or split commitments become active.\n\nLimitations\n\n- You can upgrade the term for only active commitments.\n- You can't upgrade the term for software license commitments.\n\nPerform a term upgrade\n\nUpgrade your commitment's term by using the gcloud CLI,\nGoogle Cloud console, or the Compute Engine API.\n| **Note:** If you are using the gcloud CLI or the Compute Engine API to upgrade a commitment's term and also want to [enable auto renew](/compute/docs/instances/renew-commitments-automatically) on that commitment, then you must do so using two separate operations. You can perform these two operations at the same time using the Google Cloud console, but on the gcloud CLI or the Compute Engine API, you must enable auto renew either before or after you upgrade the commitment's term.\n\nPermissions required for this task\n\nTo perform this task, you must have the following\n[permissions](/iam/docs/overview#permissions):\n\n\n- `compute.commitments.update` on the project or organization. \n\nConsole\n\n1. In the Google Cloud console, select the project where you want to\n upgrade your commitment's term, and go to the **Committed use discounts**\n page.\n\n [Go to Committed use discounts](https://console.cloud.google.com/compute/commitments)\n2. To initiate the term upgrade operation for a commitment, select an active\n hardware commitment in the **Hardware commitments** tab of the\n **Commitment list** page and click\n event_available **Upgrade**.\n\n - Alternatively, you can click the name of the active commitment that you want to upgrade. After the **Hardware commitment details** page opens, click event_available **Upgrade**.\n3. In the **Upgrade committed use discount** pane that appears, verify the\n **New end time** of your modified commitment and click **Upgrade**.\n\n4. To finish the term upgrade operation and return to the **Commitment list**\n page, in the **Upgrade your commitment?** dialogue that appears, review\n the terms and conditions and then click **Upgrade**.\n\ngcloud\n\nTo upgrade your commitment's term, use the\n[gcloud compute commitments update command](/sdk/gcloud/reference/compute/commitments/update)\ncommand with the `--plan` flag. \n\n```\ngcloud compute commitments update COMMITMENT_NAME \\\n --plan=36-month \\\n --region=REGION \\\n --project=PROJECT_NAME\n```\n\nReplace the following:\n\n- \u003cvar translate=\"no\"\u003eCOMMITMENT_NAME\u003c/var\u003e: the name of the commitment whose term you want to upgrade.\n- \u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e: the region of your commitment whose term you want to upgrade.\n- \u003cvar translate=\"no\"\u003ePROJECT_NAME\u003c/var\u003e: the name of the project for which you want to upgrade the commitment.\n\nFor example, consider a 1-year commitment, `commitment-upgrade-example`, in\n`us-central1` region and for the project `project-upgrade-example`. The\nfollowing gcloud CLI command upgrades the commitment's term and\nmodifies it into a 3-year commitment. \n\n```\ngcloud compute commitments update commitment-upgrade-example \\\n --plan=36-month \\\n --region=us-central1 \\\n --project=project-upgrade-example\n```\n\nREST\n\nTo upgrade your commitment's term, use the\n[`regionCommitments.update` method](/compute/docs/reference/rest/v1/regionCommitments/update). \n\n```\nPATCH https://compute.googleapis.com/compute/v1/projects/PROJECT_ID/regions/REGION/commitments/COMMITMENT_NAME\n{\n \"name\": COMMITMENT_NAME,\n \"plan\": \"THIRTY_SIX_MONTH\",\n}\n```\n\nReplace the following:\n\n- \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e: the project ID of the project where you want to upgrade your commitment's term.\n- \u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e: the region of the commitment whose term you want to upgrade.\n- \u003cvar translate=\"no\"\u003eCOMMITMENT_NAME\u003c/var\u003e: the name of the commitment whose term you want to upgrade.\n\nFor example, consider a 1-year commitment, `commitment-upgrade-example` in\n`us-central1` region and for the project `project-upgrade-example`. The\nfollowing Compute Engine API request upgrades the commitment's term\nand modifies it into a 3-year commitment. \n\n```\nPATCH https://compute.googleapis.com/compute/v1/projects/project-upgrade-example/regions/us-central1/commitments/commitment-upgrade-example\n{\n \"name\": \"commitment-upgrade-example\",\n \"plan\": \"THIRTY_SIX_MONTH\",\n}\n```\n\nWhat's next\n\n- Learn how to [renew commitments automatically](/compute/docs/instances/renew-commitments-automatically).\n- Learn how to [extend the term length of resource-based commitments](/compute/docs/committed-use-discounts/extend-commitment-term).\n- Learn how to [merge and split resource-based commitments](/compute/docs/instances/merge-and-split-commitments).\n- Learn how to [analyze the effectiveness of your CUDs](/billing/docs/how-to/cud-analysis-resource-based)."]]
