Change the plan of a VM

Move an hourly TIR Virtual Machine to a plan with more or fewer GPUs, vCPUs, or memory when its work outgrows the plan, or when it needs less. You stop the VM, pick the new plan, and the VM starts again on it with its disk as it was. On a committed VM, the same screen sets what happens when the term ends.

Before you begin

• An hourly VM that is Stopped. See Stop, start, and restart a VM.
• Permission to update VMs in the project. See TIR Access Control.
• On a prepaid account, credit for the new plan in your balance.

Choose the new plan

1. Open the VM’s Actions menu in Manage VMs, or More Actions on its details page, and choose Update Plan.

2. Check the current plan under Overview of the VM at the top.

3. Choose the new plan. On GPU or CPU, choose a plan, then a Configuration, then how to pay under VM Pricing: On-Demand bills by the minute at its hourly price, and a committed term is paid upfront. On Private Cluster, choose one of your own private clusters, then a configuration. See Billing options for TIR Virtual Machines to compare the ways to pay.

4. Select Update.

5. If you chose a committed term, confirm it in Committed Plan Confirmation. Tick the box that accepts the full amount charged upfront and no refund for the remaining days. Then choose what happens when the term ends. The first choice is the default:

   • Auto renewal of this committed plan buys the same plan again if your credits cover it, and otherwise switches to hourly billing and emails the owner.
   • Auto start hourly billing for this machine keeps the VM running and bills it by the minute at the hourly rate.
   • Auto deletion of this committed machine deletes the VM and its disk, so copy out anything you need first.

   Select Proceed. See Billing options for TIR Virtual Machines for more.

For the messages an update can show and what to do, see Please stop your VM before updating it.

What happens after the update

The VM starts again by itself on the new plan, going from Waiting to Running. The disk and its files, the SSH keys, the datasets, and the shared file systems stay as they were.

Billing on the new plan starts when the VM is ready. On On-Demand, that is the new plan’s hourly price. On a committed term, the term starts and its full price is taken at that moment.

The new plan is under Overview > Plan Details on the VM’s details page.

Change what a committed VM does when its term ends

1. On the list, open Actions on the VM’s row and choose Update Committed Plan. On the details page, choose Update Plan in More Actions. A committed VM keeps its configuration until the term ends, so only this choice can change.
2. Under Update Preference, in Select Committed Policy, choose what happens when the term ends: renew the term if your credits cover it, move to hourly billing at the price shown, or delete the VM and its disk.
3. Select Update.

The choice you saved is the VM’s Renewal Preference under Plan Details. For what each choice does, see Billing options for TIR Virtual Machines.

To move an hourly VM to a committed term and keep its plan, see Convert a VM to a committed plan. For other messages, see Troubleshooting TIR Virtual Machines.
