The text discusses the CockroachCloud API, which allows users to seamlessly transition between CockroachDB Basic and Standard plans without downtime. The API is suitable for upgrades and downgrades within the same region, but backup and restore can also be used in such scenarios, particularly if a fresh start or rollback from a ransomware attack is needed. When migrating to a different region, backup and restore is the only option available. The text provides step-by-step instructions on how to use the API for upgrading from Basic to Standard and downgrading from Standard to Basic. Key considerations when migrating include private link and endpoint connectivity, zero downtime, backup and restore flexibility, cost optimization, and regional migrations. Understanding when to use the API versus backup and restore is crucial for informed decision-making that aligns with business needs.
