PRACTICAL FIELD GUIDE
Release a schema change with client compatibility in mind
A schema change and a client deployment may not reach every user at the same time. Plan for old clients and open tabs when changing field names or required values.

Put it into practice
- Inventory callers that use the affected table and fields.
- Choose an additive or staged transition where needed and test both old and new request shapes.
- Retire obsolete fields only after confirming the relevant clients have moved.
What this looks like
ILLUSTRATIVE EXAMPLE
A new required field is introduced before older clients know to send it. A compatible default or staged rollout can prevent avoidable failures.
A boundary to keep clear
A successful migration does not prove compatibility with every deployed client version.
MCPBackend context
Managed hosting and a portable export solve different operational needs. Write/storage caps block writes, while the API-request cap blocks data requests including reads. The exported runtime covers compatible CRUD, auth and row policies; it does not include the hosted dashboard, MCP server, webhooks, billing, metering or managed backups.
Take the next step
Inspect the current project contract, try the change with disposable data, and verify the result through the same credentials your app will use. Record the expected response and one denied-access case before release.
