Issue: Gravity Forms Update and deprecated tables.

I ran into an issue with a site when installing Gravity Forms, it resulted in an error with trying to upgrade. Looking further under system tools, it was trying to migrate a table named wp_rg_lead_meta which didn’t exist.

I searched everywhere to try and find the table to create a statement in some sort of MySQL schema file. Lucky I found this article on the Gravity Forms site
