The Rollback
command reverts a family from its current version to a previously installed version in the current environment. Repeated use of the command will revert the version to the version installed prior to the current version (for example, if a family was installed with version 1, then updated to version 2, and finally to version 3, executing a rollback would revert the family to version 2 and another rollback would revert the family to version 1).
