Resize a Server (Upgrade Plan)

Overview

LightYear supports vertical scaling — upgrading a server to a larger plan. Downgrades are not supported; create a new server and migrate data instead.

Before You Resize

1. Snapshot your server — go to Server → Snapshots → Take Snapshot.
2. Notify users — the resize requires a reboot (typically 2–5 minutes of downtime).
3. Check disk space — the new plan must have equal or larger storage.

Performing the Resize

1. Navigate to Servers and click your server.
2. Click Settings → Resize Server.
3. Select the target plan.
4. Click Resize Now.

The server will shut down, be migrated to the new plan, and restart automatically.

Post-Resize Steps

Extend the Filesystem

After resize, the partition table is updated but the filesystem may not fill the new disk automatically:

$# For ext4
$resize2fs /dev/vda1
$
$# For XFS
$xfs_growfs /

Verify:

$df -h /

Billing After Resize

Billing switches to the new plan rate immediately after the resize completes. The old plan rate is charged up to the moment of resize.
