If you migrated the site from one server to another, the issue is going to be the database tables related to your Gravity Forms form meta data.
What did you use to migrate the database? Did you use PHPMyAdmin to export and import the SQL? If so some tools, PHPMyAdmin included, do not handle serialized array data properly. This means when you use PHPMyAdmin to export and import Gravity Forms form meta data... it corrupts the serialized data that makes up the form settings information.
What you can try is the Meta Recovery tool. It is available for download on the Plugin Downloads page here:
Download, install and activate that plugin. It will add a Meta Recovery menu item to the Forms navigation. Go there, and then use it to try and fix each of your forms.
Let me know how it goes.
If you are not worried about doing this and would rather start from scratch, simply go to the Gravity Forms Settings page (Forms > Settings) and then choose the Uninstall option at the bottom of that page. This will completely remove Gravity Forms data from your site.
Once you Uninstall, then go to the Plugins page and Activate Gravity Forms again. It will then re-build it's database tables.
