摘要
A method for upgrading software in a shared data store comprises a reliable, safe in-place method of transformation of metadata in which a metadata catalog is cloned, stored in the data store, and the cloned metadata is transformed in-place using the data store engine and SQL declarative language. The original and transformed cloned catalog files are swapped atomically, and the system upgrade is validated using the new version of software. If errors are encountered during the upgrade, the original catalog can be swapped back and the system returned to its original state.
