Resize

Open the machine → Resize tab.

What you can move to

The list shows the plans for this machine's location and instance family: a General Purpose machine is offered other General Purpose plans, a High Frequency one gets High Frequency plans. Each row shows vCPU, RAM, storage and bandwidth, the monthly and hourly price, and the difference against what you pay today.

You can move to a bigger plan (Upgrade) or a smaller one (Downgrade), as long as the plan has at least as much disk as your VPS. A disk never shrinks, so plans with less disk are greyed out with the note "This plan has less disk than your VPS".

The disk only grows if you choose to

A resize changes CPU, RAM and price. The disk keeps its size: when the new plan includes more disk, the box Also grow the disk appears, unticked.

• Unticked: the disk stays as it is, and later you can move back to a smaller plan it fits in. This is the option for scaling up during a busy period and coming back down after it.
• Ticked: the disk grows to what the new plan includes. It cannot be undone: from then on you can only move to plans with at least that disk.

If your current plan includes more disk than your VPS has, you can grow it at any time: select your plan (Current Plan) and click Grow disk.

Note

You pay the plan's price whether or not you grow the disk. The disk the plan includes that you haven't grown stays available to grow whenever you want, at no extra cost. To pay less, move to a smaller plan your disk fits in.

Resize the machine

Select the target plan, decide whether to grow the disk, click Resize and confirm. The confirmation says what happens to the disk: "Disk: kept at 100 GB" or "Disk: grown from 100 GB to 200 GB".

Warning

The machine restarts automatically during the resize. Expect a few minutes of downtime and make sure your services start on boot.

When it finishes, the machine is back online on the new plan. If it was stopped, it stays stopped and runs on the new plan when you start it.

After the resize

• If you grew the disk, some operating systems need the partition and filesystem extended to use the new space. Check with df -h after the reboot.
• Billing switches to the new plan's hourly rate.
• Reinstalling the OS or restoring a backup keeps the current disk size.
• The event is recorded in Activity.

Tip

Before resizing for performance, check Metrics to confirm which resource is actually the bottleneck. A machine that's swapping needs RAM, not vCPUs, and buying the wrong axis costs money without fixing anything.
