Existing Database Migration

Scenario

When upgrading from an old database, complete the following checks before migration:

Confirm source database version and target version compatibility.
Count API Keys, channels, models, Route Policies, Usage Log records, and Audit Log records.
Check whether there is invalid JSON, duplicate name, or orphaned relationship data.
Run migration rehearsal on a copied database.
Record the migration duration and disk growth observed during rehearsal.

After migration, verify that key metadata can be queried from the Console UI and that new requests can be written to Usage Log and Audit Log.

Run migration rehearsal on a copied database before production migration. Do not use the production database for rehearsal.
