What happens when you choose the Refresh upgrade option?

• A. It upgrades only the schema
• B. It migrates to a new environment
• C. It erases the MST and creates a new copy from TST or PRD
• D. It performs a data clean-up

Answer: (C)

Refreshing the upgrade option performs a full rebuild of the environment by wiping the current MST (the main structure/configuration) and pulling a fresh copy from a source environment such as Test or Production. This means the environment is reset to match that source exactly, including its schema, metadata, and data, giving you a clean, known-good baseline. It is destructive: any local changes or data in the current environment are replaced by the source copy. This isn’t just upgrading the schema, nor merely migrating to a new environment or performing a simple data cleanup. It’s resetting to a mirror of the chosen source.
