Yes. To upgrade your VPS:
- Log in to unified.sableservers.com and open your VPS.
- Open Current Plan and click Upgrade Plan.
- Pick the plan you want.
- Choose Upgrade Now (Prorated) to pay a prorated charge for the rest of this cycle, or Schedule for Next Cycle.
- Confirm with Yes, Upgrade.
Note: the new CPU and memory are only available after the VPS is power cycled, which takes about 15 seconds of downtime. The panel lets you reboot now or schedule it for later.
To downgrade, click Downgrade Plan. Downgrades take effect at the end of your current billing cycle, and your disk usage must fit the smaller plan. Back up your data before any plan change.
