Sandbox Explained
Salesforce offers four sandbox types, each with different data and metadata capacities. Developer sandboxes include metadata only and are ideal for isolated feature work. Developer Pro sandboxes add a larger data storage limit for integration testing. Partial Copy sandboxes use a sandbox template to pull a defined subset of production data. Full sandboxes clone everything (metadata, data, and files) and are used for final UAT, performance testing, and staging.
Sandboxes refresh on a schedule that depends on their type: Developer sandboxes can refresh daily, while Full sandboxes require a 29-day minimum interval. Change sets, the Metadata API, and Salesforce DX (with scratch orgs as a complement) are the primary mechanisms for migrating work from sandbox to production. Clientell AI can deploy changes across your sandbox pipeline, track what has been promoted, and flag configuration drift between environments automatically.
