Downgrade Plan
Plans are upgrade-only. Downgrades are not supported. Attempting to move to a lower tier returns downgrade_not_supported.
Why
A higher tier holds more atoms than a lower one — for example, Professional stores up to 100,000 atoms and Solo up to 10,000. A larger substrate cannot be fitted onto a smaller one without dropping atoms, and losing your memory is not an acceptable outcome. Rather than silently delete or partially migrate your data, we do not offer downgrades at all.
What to do if you need a smaller plan
- Stay on your current tier. You pay only your monthly price — there is no penalty for having headroom you are not using.
- Reduce your bill by reducing usage. Your bill is the flat tier price plus any metered atom overage. Tombstoning unused atoms via
session_checkpointlowers overage charges, but it does not change your base tier price. - Start fresh on a smaller plan. If you genuinely want a lower tier, export your atoms, cancel, and sign up again at the smaller tier, then re-import only what you need. Cancellation deprovisions your instance and takes a snapshot with no free grace period, so export first — see Cancel Subscription.
