The Full Copy sandbox is acting as Universal Containers ' final regression and staging environment. It should therefore be refreshed after a major release reaches production so the environment again represents the current production baseline before development for the next release cycle proceeds. Salesforce states that refreshing a sandbox replaces it with a current copy of its source production organization, updating metadata and, for Full sandboxes, production data. Salesforce ' s current sandbox strategy guidance also recommends refreshing staging and deployment sandboxes after production upgrades to keep environments aligned. Refreshing after every Partial Copy deployment would unnecessarily destroy the staging environment ' s current testing work, while adding a single production user does not justify a Full sandbox refresh. Refreshing only after UAT also occurs too late in the stated lifecycle. Salesforce
