UPGRADE_MODEL

Upgrades a model from a previous Vertica version. Vertica automatically runs this function during a database upgrade and if you run the IMPORT_MODELS function. Manually call this function to upgrade models after a backup or restore.

If UPGRADE_MODEL fails to upgrade the model and the model is of category VERTICA_MODELS, it cannot be used for in-database scoring and cannot be exported as a PMML model.

This is a meta-function. You must call meta-functions in a top-level SELECT statement.
